The code below should compile with no errors.

This is related to the other gagging bugs (bug 4269, bug 5932, bug 4197, bug
5996). I think that every template needs to record whether it is an
investigative template or not. If it is, it shouldn't be considered to be
instantiated.

-----
template Compileable(int z) { bool OK;}

static assert(!is(typeof( Compileable!(Bug6262!(int).bar()) )));

struct Bug6262(T)
{
   int bar() { T.codswallop(); return 3; }
}
