Heh heh heh.  :-)

Yeah all of these offend my eyes and I secretly hope that I can convince
everyone whose code I have to read to abjure them.

P.S.  I'm convinced there is a neurological difference between people who like
Perl and people who like Python.  All of the suggested syntaxes above cause my
Perl-hating synapses to fire wildly.  Note that I, Ppooko, don't even
understand what these are supposed to be accomplishing (something about
appending or inserting elements?  Like `.append()' and `.insert()' do in
Python?), but I don't care.  I just wanted to mention that the very shapes of
those tokens cause my pupils to spasm.
