With and without `version=expected`, this code should work, but doesn't.
bool foo(alias pred)()
{
version(expected)
{
// doesn't work, but should
enum isLessThan = (is(typeof(pred) : string) && pred == "a < b");
}
else
{
// works as expected
static if (is(typeof(pred) : string) && pred == "a < b")
enum isLessThan = true;
else
enum isLessThan = false;
}
return isLessThan;
}
void main()
{
assert(foo!("a < b")() == true);
assert(foo!((a,b) => a<b)() == false);
}
Manifest constant declaration is always evaluated in compile time, so I think
there is no problem.
