Still not sure, if I get you right...

import std.stdio;

void main() { auto res = myTemp!(C.s); }

class C { static size_t s; }

template myTemp(alias s) { enum myTemp = 
templateFunction!(typeof(s))(s.stringof); }

int templateFunction(T)(string targetMembername)
	static assert(is(T == size_t));
	assert(targetMembername == "s");
	return 42;

In general, I'm not sure, how you want to get a type of a general 
symbol (this is what templateFunction should do, isn't it?) as it 
could be a template or a value parameter for example.
However, I tried these cases, and typeof yields something 
reasonable then. In particular, it still did compile and yields 
something which could be checked against...
