Poll: Which 3 languages would you learn

A lot of the comments to a recent post (http://news.ycombinator.com/item?id=1982903) suggested that they would like to see a similar poll for HN, so here it is. I don't want to restrict the choices and will collate the data in the replies. THREE languages per reply, please

Let me broaden it a little and also ask the optional question: Which new natural language(s) would you like to learn and why (i.e., other than your native language an the ones you are fluent in)

  - C
  - Java
  - Python

Optional: Japanese, probably. I thought of learning a new language for some months but am still unsure which. Maybe this thread gives some idea :)

Java, Javascript, C++

I know this selection seems passe but here's my rationale: First, learn a lingua franca that (almost) everybody knows and has huge libraries. That would be Java. Java is the English of computer languages, I think.

Javascript not only has immense presence (the default selection?) in most web development, and is gaining prominance in developing on mobile devices, e.g. bypassing the whole Objective-C & Cocoa stuff for iPhone and iPad. I don't know it much, but it also seems like an interesting language.

The third choice is not that clear, depends on whether you want to have an all-powerful language (C++) or one that excels in concurrency (e.g. Erlang) or want to expand your horizons (Scheme or Haskell, perhaps), etc. etc. I use C++ daily and if I had to do again I would still select it, but I may be biased because I am doing image and video analysis work.

As for natural languages: If you are interested in linguistics, I think you've got to learn Ancient Greek, to see a lot of the complexity and mechanisms that has been lost in other IE languages (you can, of course learn Lithuanian or Hittite for even a better grasp, but sources to those are harder to find and the reading material would not be as exciting, I think :-). It was an eye opener for me. As a second choice, I would go with Chinese, for the mind-expanding aspect (did you know that Chinese speakers can roughly classify the meaning of a word even if they don't its meaning, using radicals?) Also, you prospects for a job get multiplied 10x.

Haskell, Erlang, Ocaml

Python, Haskell, and actually master C
