You can't.

Gods, no!  You do not.  Why on earth would you think you want a dedicated,
stande-alone program for this?!

Oh, you just want to MINIMIZE TYPING.  Then write a series of shell

wooledg:~$ sin() { perl -e 'print sin $ARGV[0], "\n"' "$1"; }
wooledg:~$ sin 1

This is what shell functions are for.  You can just drop the shell
functions into your ~/.bashrc and then use them in every interactive
shell thenceforth.

I strongly recommend this approach over the aliases that were previously
suggested, by the way.  Functions are so much cleaner.
