< simon__> hello. I'm trying to make a list of lists with gather for
but it keeps flattening the result. can someone tell me what i'm doing
wrong?
<masak> simon__​: maybe make a list of arrays instead?
<masak> lists of lists often flatten, because Perl works that way.
<masak> nom​: say (gather { take [1..$_] for 4..6 }).perl
<p6eval> nom eb6c4b​: OUTPUT«(1, 2, 3, 4, 1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 6).list␤»
<masak> huh.
<simon__> that's what i've been doing
<masak> nom​: say (gather { take [[1..$_]] for 4..6 }).perl
<p6eval> nom eb6c4b​: OUTPUT«([1, 2, 3, 4], [1, 2, 3, 4, 5], [1, 2, 3,
4, 5, 6]).list␤»
<masak> using double layers seems to work.
<sorear> eheheheh... I don't think it should work that way
<masak> but no, it seems wrong that it works so from the start in nom.
<masak> probably a bug.
<sorear> b​: say (gather { take [1..$_] for 4..6 }).perl
