I think Lisp is missing in that list, but while struggling to read it I don't hate it. (Others will certainly differ)

While being one of the two oldest languages it's still alive and very influential.

Learning Lisp made me a better programmer and most of my struggles seem to be related to arcane properties of eLisp.

(I recommend reading Higher Order Perl)

Should be mentioned that Larry mentioned Lisp as one of his influences while designing Perl.
