Is this preferred design pattern?``` int main() { int a = 1;//ref int b = a; // Error: variable `tst_ref.main.b` only parameters or `foreach` declarations can be `ref`ref int b() { return a; } b = 2; assert(a == 2); return 0; } ``` Fanda
It's okay, but I'd prefer an alias, because your snippet uses the heap needlessly (it puts variable a into heap to make sure there will be no stack corruption if you pass a pointer to function b() outside the main() function)
