colomon: Lots of stupid little math tests are failing because we cannot define constants yet (as far as I know), so no pi, i, or e.
Now have pi and e, i is probably least important.

colomon: ng: my $a; say $a ~ “hello”
[11:13am] p6eval: ng 46e2ef: OUTPUT«Mu()hello␤»

colomon: sink context should be eager.
