3448 – `__traits(compiles, <uncompilable template>)` is true and doesn't gap errors if not in a function

template Bar()
{
 void Bar()
 {
 error;
 }
}
template Foo()
{
 enum Foo = __traits(compiles, Bar!());
}
static assert(!Foo!());

This seems to have the same root cause as bug 965

Just a bit smaller testcase:
---
void t()() { error; }
static assert(!__traits(compiles, t!()())); // assertion fails
static if(__traits(compiles, t!()())) { } // Error: undefined identifier
---

This bug is only for `static assert/if` not in a function:
---
void t()() { error; }
void f() {
 static assert(!__traits(compiles, t!()())); // passes
 static if(__traits(compiles, t!()())) { } // no errors
}
---
