isInputRange looks like this:
template isInputRange(R)
{
enum bool isInputRange = is(typeof(
(inout int = 0)
{
R r = R.init; // can define a range object
if (r.empty) {} // can test for empty
r.popFront; // can invoke popFront()
auto h = r.front; // can get the front of the range
}));
}
If I change the `enum bool` line to `enum bool isInputRange =
true && is(typeof(`, all is fine.
If instead I:
enum foo = true;
enum bool isInputRange = foo && is(typeof(
Then:

Surely they should be identical? Obviously I was trying to do
something else with an enum, but this is the reduced sample.
