Per ECMAScript standard (ECMA-262, referenced by SQL standard), the
syntax forms
.1
1.
should be allowed for decimal numeric literals, but the existing
implementation rejected them.
Also, by the same standard, reject trailing junk after numeric
literals.
Note that the ECMAScript standard for numeric literals is in respects
like these slightly different from the JSON standard, which might be
the original cause for this discrepancy.
A change is that this kind of syntax is now rejected:
1.type()
This needs to be written as
(1).type()
This is correct; normal JavaScript also does not accept this syntax.
We also need to fix up the jsonpath output function for this case. We
put parentheses around numeric items if they are followed by another
path item.
