push @bar, [splice @foo,0,$cols] while @foo;
It has the disadvantage of being destructive of @foo, but it's ever so
much easier on the eyes (well, my eyes, anyway).
And then once you have the 2D array of rows, you'll need (unless this
feature's crept in while I wasn't looking) to transform it to an array of
hashrefs with the sub-loop under the appropriate key:
$tmpl->param( loop => [ map +{subloop => $_}, @bar ]);
This puts me in mind of a feature I was once planning to either ask for or
attempt to produce (and may yet): some analog to $_ for HTML::Template
loops. I don't know how common a situation is is, but loops with exactly
one parameter (be it a sub-loop or a single TMPL_VAR) seem to occur
frequently in my (relatively limited) use of H::T. Being able to use
something like <TMPL_VAR _ > and pass an arrayref to param() instead of
mapping it to an AoH would produce a small but measurable improvement in
my quality of life. Is this something that's been looked at before and
decided against, or would it be worth contemplating next time I have
coding time on my hands?
