Wait, *that's* the case against MUMPS? I mean, I keep hearing how ugly it is to work with, and I believed it, but...
They seem so horrified as they list off features: case sensitivity! dynamic typing! perl-style automatic string/number coercion, and a built-in database system! It has 'eval', what a bizarre and unprecedented idea! Granted the lack of operator precedence is a little weird, and the old mainframe-style length limitations on names are a hassle to work with, but these are the features that make it an "esoteric joke language"?
I sort of get the feeling that to Alex Papadimoulis, "esoteric joke language" means "the name doesn't rhyme with 'lava'".
Maybe some of the code is obscurely written, I don't know, but if it's obscure and it works well then that's much better than most hacked up software designed to do boring mainframey work.
