* Note that compiler_mod() suggests module, but the module ast type
* (mod_ty) has cases for expressions and interactive statements.
*
* CAUTION: The VISIT_* macros abort the current function when they encounter
* a problem. So don't invoke them when there is memory which needs to be
* released. Code blocks are OK, as the compiler structure takes care of
* releasing those.
