Restricting Perl to have a code block prototype (&) only at first position is hindering many options for syntactic sugar.

Be it more expressive versions of 'map' and 'grep' or 'loop' constructs. Basically because you want to add a modifier between keyword and block, without needing to explicitly introduce ', sub' .

Your rant about the limits of Ruby may be legit, but had little or nothing to do with what I said or meant.
