           Summary: __traits(compiles) returns true for uncompilable code
                    due to static assert

void foo()
{
    static assert(false);
}

void main()
{
    static assert( __traits(compiles, foo()) == false );
}

The assert fails, but should not. Looks similar to bug 3448.

Assertion in `foo` should fail because `foo` is a regular function and compiles
independently of assertion in `main`. This code compiles:
---
void foo()() { static assert(false); }
void main()  { static assert(!__traits(compiles, foo!()())); }
---

Note, that due to bug 3448 __traits(compiles) works correctly only if it is in
a function.
