In some strange ways I wish I never had. And I'm truly not being overly hyperbolic when I say I struggle to enjoy programming in other languages.
I can do it but I can just never quite make the other languages fit how I want to think about the problems.
I think one major barrier is that nearly every language I have to use is lumbered with truly horrible data handling with the pervasive OO model that is so bad. I've used CLOS too much to never look at OO the same again.
And then if I'd rather just think of things as name/value collections, Clojure is just so easy.
