void main()
{
	void function() func;

	foreach(mem; __traits(allMembers, extra))
	{
		static if(__traits(compiles, mixin(mem)))
		foreach(att; __traits(getAttributes, mixin(mem)))
		{
			if(att == "good") func = &mixin(mem);
		}
	}

	if(func) func();
	else writeln("func not assigned");
}

This works for me. DMD 2.064.2
