:blocks do.
On the other hand, there is also the possibility now that you end up
with:
{
# couple of lines here
}
# 100 lines of comments here
finally { ... }
I think it's unwise to try to mitigate every case of "100 lines here",
it seems like a short road to madness. But if you want to avoid it in
this case, I think you'd need yet another keyword. I'm not convinced
that the language is improved by tacking an optional continuation onto
bare blocks.
Either way, I do think we should be encouraging Perl developers to write
their code so as to minimize confusion, eg by factoring away "100 lines
here".
