No, install them again with apt-get.  Perl is a pretty vital part of a
debian system, but a full perl system isn't installed by default;
instead you just get the perl-base package which contains the perl
interpreter and just enough to be able to run basic perl scripts.  You
also won't have lost any config files as apt-get remove won't remove
them unless you specifically tell it to (with --purge).

Debian also gives you a pretty harsh warning if you /do/ try to remove
all of perl:

uml-sid:~# apt-get remove perl perl-base

If you do type Yes, do as I say! you end up, surprisingly, with a system
that still boots - although I'd guess from the list above that if you
actually required LILO to boot you'd be in strife (as opposed to the
system I tested it on, which was a User-Mode Linux virtual machine - so
I could restore it to its original state by removing the COW file).  You
won't be able to do much with the resulting system, either - the network
won't come up on boot, and most interesting packages require perl either
directly or indirectly.

Ohhh, yes it is.  I hope you kept a list of what got removed :-/  BTW
even at this point, /don't/ bother reinstalling by wiping your system
clean and reinstalling Debian - it'd be even more hassle overall.
