Features like this are not used very often in C and do make a language more complex than needed. So it was removed.

If it has visibility of local variables, then we are talking about a closure rather than a function and when you want to have closures in your language, you need to be wary of many factors, for example:

• Do you clone the values of the local vars as they were when the closure was created?
• Do you keep a reference or move them into the closure?
• Can the closure be freed? If so, how? You probably wouldn't want a memory leak

Solving these is probably beyond the scope of this language.

This C feature is only in GCC/Clang or?
