I also love Haskell's syntax. It's very tasteful in most choices. Although my opinion of Python has gone down over the last few years, I still like its syntax, too. Especially the significant indentation, but I believe that Haskell has the slightly better mechanism, by defining indentation as a syntax sugar that you can avoid, if you want to.

OCaml's standard library is also quite dismal. At the recent meeting of the OCaml consortium in Paris we suggested creating a new extended standard library. (We will reuse Core and Batteries et al, of course.)

A co-worker and I are in the procss of writing a regular expression module that doesn't suck. It will be threadsafe and use poor OCaml---the module from the standard library calls C-code to run a backtracking bytecode interpreter with lots of mutable state.
