Bug 8942 – `alias <qualifier> <type>` ignores <qualifier> in foreach over tuple

Qualifier is ignored in foreach over tuple if there is no parantheses: --- alias const int A0; static assert(is(A0 == const int)); // passes void main() { alias const int A1; static assert(is(A1 == const int)); // passes static struct S { int i; } foreach(Unused; typeof(S.tupleof)) { alias const(int) A2_; static assert(is(A2_ == const int)); // also passes alias const int A2; static assert(is(A2 == const int)); // fails // Error: static assert (is(int == const(int))) is false } } --- As always, such (unexpected) template bugs are hard to figure out.
