#replace_include!(include_ast, isa_ast) ⇒ Object

replaces an include statement with the ast in that file, making it a direct child of this IsaAst

#type_check(symtab) ⇒ void

This method returns an undefined value.

type check this node and all children

Calls to #type and/or #value may depend on type_check being called first with the same symtab. If not, those functions may raise an AstNode::InternalError
