Description Zhenya Chapovsky 2013-01-06 05:55:10 UTC 
struct OhWhy(S) {
   S[] arr;
   alias arr this;
}

void main() {
    static assert(!is(OhWhy!float unused == T[],T));/*fails,but shouldn't
since struct OhWhy isn't an array */
}

Reduced testcase
---
struct S
{
    float[] arr;
    alias arr this;
}

static assert(!is(S == float[])); // ok
static assert(!is(S == T[], T)); // fails
