Hi All,

Request your help on hot to create a pointer for a function whose function type is Result.

ReturnType!(typeof(&test)).stringof; // Result

To get a function pointer type from a function type, you can add * on the end:

void func(int) {}

alias FuncType = typeof(func);
pragma(msg, FuncType); // void(int)

alias FuncPtrType = FuncType*;
pragma(msg, FuncPtrType); // void function(int)
static assert(is(FuncPtrType == typeof(&func)));

Thank you very much
