<masak> r: X[X]
<p6eval> rakudo e765c9: OUTPUT«===SORRY!===␤Method 'parameterize' not

That doesn't feel like an error message that should show up in that situation.

<masak> std: X[X]
<p6eval> std 64edd1c: OUTPUT«===SORRY!===␤Undeclared name:␤    'X'
used at line 1,1␤Check failed␤FAILED 00:00 42m␤»

Something like this would be better.
