have you tried to double ()

Ya, I thought of that right after posting and it does fix the compilation error. The issue I'm having now is that both

has_foo_ctor< Foo >::value has_foo_ctor< Bar >::value

are evaluating to true and I'm not sure why.

When you use double parentheses, it calls the comma operator and only passes a single argument to the constructor. In Christ, Steven Watanabe
