I ran into trouble with this example as well, but this time because what should
work, doesn't:

import std.stdio;

template isNumeric(T)
{
  enum bool test1 = is(T : long);
  enum bool test2 = is(T : real);
  enum bool isNumeric = test1 || test2;
}

void main()
{
  bool a = isNumeric!int;
}


Fails with:
test.d(12): Error: expression isNumeric!(int) is void and has no value.

I was surprised to find that the language reference actually contradicts TDPL
here:

"Implicit Template Properties
If a template has exactly one member in it, and the name of that member is the
same as the template name, that member is assumed to be referred to in a
template instantiation."
