<masak> std: 1, 2, 3, given 4
<p6eval> std a194beb: OUTPUT«ok 00:01 120m␤»
<masak> rakudo: 1, 2, 3, given 4
<p6eval> rakudo 015d77: OUTPUT«Could not find sub &given␤  in main
program body at line 22:/tmp/ipNXhbYj50␤»
<masak> which one's right, STD or Rakudo?
* masak submits rakudobug
<sorear> looks like rakudo is missing terminator:sym<given>
<jnthn> Ah
<sorear> digging deeper, it looks like the problem is in
HLL::Grammar.nulltermish
<sorear> which doesn't check <?terminator>
