I would say low level languages, and pure functional languages, and other unusual things are an exception. I don't see how anyone could use Haskell or Scheme and especially not Forth without lots of experience in that specific paradigm, and lots of programmers don't prioritize learning languages they don't expect to encounter. They say Haskell makes you a better programmer, but does a lack of it make you a bad programmer?
