Re^2: [OT]: This does not look like start end (grep vice for)

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.

... switched from grepping into a single array to push @a...; push @b...;.

But there are many examples of statements like  grep { $_=0 } @acopy; Very strange.
