Creating a lambda and assigning it immediately to a name is not all that useful, but lambdas can be used whereever an expression is expected.

### Embedding Kuroko

Kuroko is built as a shared libary, `libkuroko.so`, which can be linked against. `libkuroko.so` generally depends on the system dynamic linker, which may involve an additional library (eg. `-ldl`).

Strings, functions, closures, classes, instances, and tuples are all basic objects and carry additional data in their heap representations.

_Strings_ (`KrkString`) are immutable and deduplicated - any two strings with the same text have the same _object_. (See _Crafting Interpreters_, chapter 19) Strings play a heavy role in the object model, providing the basic type for indexing into attribute tables in classes and instances.

_Functions_ (`KrkFunction`) represent bytecode, argument lists, default values, local names, and constants - the underlying elements of execution for a function. Generally, functions are not relevant to either embedding or C modules and are an internal implementation detail of the VM.

When attaching methods, notice the `.` at the start of the name. This indicates to `krk_defineNative` that this method will take a "self" value as its first argument. This affects how the VM modifies the stack when calling native code and allows native functions to integrate with user code functions and methods.
|
||||
|
||||
In addition to methods, native functions may also provide classes with _dynamic fields_. A dynamic field works much like a method, but it is called implictly when the field is accessed. Dynamic fields are used by the native classes to provide non-instance values with field values.

If your new instances of your class will be created by user code, you can provide an `__init__` method, or any of the other special methods described in the Examples above.

When you've finished attaching all of the relevant methods to your class, be sure to call `krk_finalizeClass`, which creates shortcuts within your class's struct representation that allow the VM to find special functions quickly:
