struct Policy{} struct Bogus(CT=Policy) { this(int dummy) { _r = 1; } } Bogus a; void main(){} dmd from git commit 54056a901cd78410b96cb9bff245c231e6d6f71e outputs: bug3.d(11): Error: struct bug3.Bogus(CT = Policy) is used as a type

the real problem is seen if replaced with: Bogus!Policy a; bug3.d(7): Error: undefined identifier _r, did you mean variable a? That's what I'd expect with default instantation too.

You didn't actually instantiate it the first time: This: Bogus a; Needs to be: Bogus!() a; It's unfortunate D doesn't allow the first case to work though.. but that's probably another bug report.
