struct Foo {}
struct Bar {
    Foo f;
    alias f this;
}
void works( T )( T value ) if ( is( T : Foo ) ) {}
void doesnotwork( T : Foo )( T value ) {}

void main( ) {
    Bar b;
    works( b );
    doesnotwork( b );
}


The 'works' function runs without problem, 'doesnotwork' does (can you guess?)
not work.
