By being told that using them would solve some problem you're
complaining about on #haskell or the mailing lists, you look at
examples, read up on them, etc.

Short version: don't worry about advanced concepts until you have to.
If all else fails, it doesn't hurt to write out the low-level version
yourself and then get told in a code review that it would be "easier" or
more elegant with an advanced technique.
