Ah, so an alternative would be to just redefine the sub:
my $str = '';
sub say($arg) {
$str ~= $arg
}
say 'hi';
use Test;
is $str, 'hi', 'works';
Works

You're getting a stack trace that's missing the helpful bits, because
they go through the core setting, and our default backtrace printer
skips those.
You can get the vital information you need by supplying --ll-exception
directly after perl6. It'll show you that calling the sub "say" will
