OK.

The problem may be related to optional parentheses and stringof, and may 
be a compiler bug.

You can pass function names as a template alias parameter:

import std.stdio;

int f(int i) {return i^^2;}

template check(alias Symbol)
{
	enum check = Symbol(5); // CTFE
}

void main()
{
     //~ pragma(msg, f.stringof); //error

     writeln(check!f); // 25
}
