  /**
     Installs a StructBinder-bound function pointer member of the
     given name and function in the given StructBinder.StructType
     target object.
     It creates a WASM proxy for the given function and arranges for
     that proxy to be cleaned up when tgt.dispose() is called. Throws
     on the slightest hint of error, e.g. tgt is-not-a StructType,
     name does not map to a struct-bound member, etc.
     As a special case, if the given function is a pointer, then
     `wasm.functionEntry()` is used to validate that it is a known
     function. If so, it is used as-is with no extra level of proxying
     or cleanup, else an exception is thrown. It is legal to pass a
     value of 0, indicating a NULL pointer, with the caveat that 0
     _is_ a legal function pointer in WASM but it will not be accepted
     as such _here_. (Justification: the function at address zero must
     be one which initially came from the WASM module, not a method we
     want to bind to a virtual table or VFS.)
     This function returns a proxy for itself which is bound to tgt
     and takes 2 args (name,func). That function returns the same
     thing as this one, permitting calls to be chained.
     If called with only 1 arg, it has no side effects but returns a
     func with the same signature as described above.
     ACHTUNG: because we cannot generically know how to transform JS
     exceptions into result codes, the installed functions do no
     automatic catching of exceptions. It is critical, to avoid
     undefined behavior in the C layer, that methods mapped via
     this function do not throw. The exception, as it were, to that
     rule is...
     If applyArgcCheck is true then each JS function (as opposed to
     function pointers) gets wrapped in a proxy which asserts that it
     is passed the expected number of arguments, throwing if the
     argument count does not match expectations. That is only intended
     for dev-time usage for sanity checking, and may leave the C
     environment in an undefined state.

       `name` property, `struct.$zName` is set to the C-string form of

  /**
     Installs a StructBinder-bound function pointer member of the
     given name and function in the given StructType target object.
     It creates a WASM proxy for the given function and arranges for
     that proxy to be cleaned up when tgt.dispose() is called. Throws
     on the slightest hint of error, e.g. tgt is-not-a StructType,
     name does not map to a struct-bound member, etc.
     As a special case, if the given function is a pointer, then
     `wasm.functionEntry()` is used to validate that it is a known
     function. If so, it is used as-is with no extra level of proxying
     or cleanup, else an exception is thrown. It is legal to pass a
     value of 0, indicating a NULL pointer, with the caveat that 0
     _is_ a legal function pointer in WASM but it will not be accepted
     as such _here_. (Justification: the function at address zero must
     be one which initially came from the WASM module, not a method we
     want to bind to a virtual table or VFS.)
     This function returns a proxy for itself which is bound to tgt
     and takes 2 args (name,func). That function returns the same
     thing as this one, permitting calls to be chained.
     If called with only 1 arg, it has no side effects but returns a
     func with the same signature as described above.
     ACHTUNG: because we cannot generically know how to transform JS
     exceptions into result codes, the installed functions do no
     automatic catching of exceptions. It is critical, to avoid
     undefined behavior in the C layer, that methods mapped via
     this function do not throw. The exception, as it were, to that
     rule is...
     If applyArgcCheck is true then each JS function (as opposed to
     function pointers) gets wrapped in a proxy which asserts that it
     is passed the expected number of arguments, throwing if the
     argument count does not match expectations. That is only intended
     for dev-time usage for sanity checking, and will leave the C
     environment in an undefined state.
