ACK!  What's with all the $@ stuff?!  This is my biggest pet peeve with
Perl.  Syntactic sugar.  Perhaps to a Perl programmer, this makes sense.
Because I have a background in shell programming, I interpret "$@" to
mean "arguments $1...$N".  Obviously wrong.

    "$@    eval error"

Ick.  Almost as bad as $_.

OK.  This makes sense.  No syntactic sugar involved.  Clean, precise.
If all Perl were like this, I'd be much happier using it.
