I'd say our worst feature is tending to give solutions which are not
"simple" Haskell, but make use of advanced features. When a beginner
asks a question, sometimes the answer requires GADT's, Template
Haskell, rank-2 types etc. However this is usually because they asked
the wrong question - thinking in an imperative frame of mind. Often it
would be better to peel back to the original problem, where the answer
is more likely to be pure neat Haskell.

I guess unsafePerformIO is just one instance of this.
