Oh, my bad: I totally forgot a crucial thing on question: I
want this to work with a static member, for example, call
myTemp like this myTemp!(C.a) I don't mind if I to pass the
type as parameter somehow, like myTemp!(C, C.a) or
myTemp!(C)(C.a) but I do need to pass a symbol as parameter,
hence I'm using alias template parameter.
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...
