Greg Wilson:
I mostly don't like suffix operators --- too easy to miss them when
reading code (especially if the thing they're being applied to is more
than a couple of symbols long).

I would rather stick to what we have than introduce two notations for
construction, call, subscripting, etc. --- Perl's [] vs. {} *always*
causes headaches for newcomers.
