opinion

I am wondering if I should continue to learn OCaml or switch to F# or Haskell.

Here are the criteria I am most interested in:

Longevity
- Which language will last longer? I don't want to learn something that might be abandoned in a couple years by users and developers.
- Will Inria, Microsoft, University of Glasgow continue to support their respective compilers for the long run?
Practicality
- Articles like this make me afraid to use Haskell. A hash table is the best structure for fast retrieval. Haskell proponents in there suggest using Data.Map which is a binary tree.
- I don't like being tied to a bulky .NET framework unless the benefits are large.
- I want to be able to develop more than just parsers and math programs.
Well Designed
- I like my languages to be consistent.

Please support your opinion with logical arguments and citations from articles. Thank you.
