To add to the evidence, I'm an experienced Python programmer who is currently waiting very impatiently for his Amazon shipment of "Real World Haskell" and "Purely Functional Data Structures". (Oh, and "Garfield Minus Garfield".)
The last of those books opens with "Objective Caml (OCaml) is a popular, expressive, high-perfomance dialect of ML...". This must be some hitherto unknown usage of the word "popular"...
