Bug 10892 – Compilation continues after static assert failing in templates

template A() { static assert(false, `error`); enum A = A!(); } void main() { enum B = A!(); } Output: Error: forward reference of variable A Error: static assert "error" instantiated from here: A!() Expected output: Error: static assert "error" instantiated from here: A!() If static assert fails and there is much code after it, it makes a trouble.

This issue is invalid. There is no order relationship between the declarations inside a template scope, so the expectation that the static assert is evaluated before the enum declaration is misguided. The general case is that the assert actually tests something that is defined inside the the template declaration scope, therefore we shouldn't expect a relationship order.
