Comment on: Using GCC's Nested Functions with Wide Pointers and No Trampolines II
Regarding function syntax in C++: GCC's C++ frontend does not support nested functions. But more importantly, even if it did, I do not think there would be any conflict at all. While lambdas are lowered to function objects with an unique anonymous type in C++, the semantics of a lambda that uses lvalue capture auto f = [&](int x) - > int { return x + z; }; is exactly the same as GCC's nested function int f(int x) { return x + z; } except that latter can be converted via a trampoline to a regular function pointer. But you could do just the same with a lambda using a trampoline! In any c
