okay. I get the idea.

I'd like we examine also the case of DECL_STMTs that seems to fall under the
For now we have a symbol table that spreads all over the tree. DECL_ nodes
define entries in this symbol table. Isn't a "stand alone" symbol table a better
representation for storing this information? It's probably a good way to store
variable declarations in C-like languages, but what about fortran and other
