Getopt::Long - simple numeric option Can't Post

It is common for many *nix utilities to have a pure
numeric option (with no identifier). For example:

grep -3 ... , which is short for grep -C 3

or

fmt -72 ... , which is short for fmt -w 72

I could not find a way to do that in perl, using
Getopt::Long::GetOptions(). Am I missing something?

I could roll my own by transforming @ARGV
before calling GetOptions(), but it seemed to
me that perl should have a facility to do pretty
much everything that standard *nix utilities do.
