-- proper handling of function pointer types
-- outermost typequalifiers can differ between function declarations and
- implementations...
+- add constant folding code (optional, ast2firm already does it)
+- Refactor code, so code to handle number values (and strings?) is an own
+ module and replacable
+- Add columns to source positions
+- SourcePositions could be stored selectively on expressions that really need
+ them.
+- check semantic for functions declared/defined in global scope and declared
+ again in a local scope
+- for errors relating to function argument, print number of argument
+- print initialisation type_path for initializer errors
