Reimplement module functions
Instead of a lambda, create a new type containing all data required to
call the function, and support it in the evaluator. Because this type
now also needs to store the function documentation, it is too big for
Lisp_Misc; use a pseudovector instead. That also has the nice benefit
that we don't have to add special support to the garbage collector.
Since the new type is user-visible, give it a predicate.
Now we can easily support 'help-function-args' and 'func-arity'; add
unit tests for these.
* src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
(XMODULE_FUNCTION): New pseudovector type 'module function'.
* src/eval.c (FUNCTIONP): Also treat module functions as functions.

functions.

functions.

that module functions are first-class objects, they deserve a

Fontify C++ for loop variable as variable, even when followed by parentheses
