Mmmm.... regular expressions....

is someone/anyone willing to help me work out this particulary nasty (to me) perl regular expression? It's kindof pissing me off...
print pack"C*",split/\D+/,`echo "16iII*o\U@{$/=$z;[(pop,pop,unpack"H*",<> )]}\EsMsKsN0[lN*1lK[d2%Sa2/d0<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<J]dsJxp"|dc`

I couldn't even get Perl to evaluate the string enclosed by ` ` on its own.

It uses dc apparently, and arbitrary mathematical library or something.... don't worry.... for those who want to know, that is the RSA encryption algorithm... in 2 lines of perl.

I'm positive that that is the scariest regular expression I've ever seen, and hopefully ever will see.
