in reply to Re: [OT]: This does not look like start end (grep vice for)
in thread This does not look like start end

My thought was that somewhere in the development line, the author had switched from grepping into a single array to push @a...; push @b...;. But I went back all the way to the v0.02 (the farthest that metacpan would take me in BackPAN), and it was still the grep { ... push ... }-in-void-context construct. So if it was the change to push that caused it, the change happened before it was tracked in CPAN.
