As I understand it Haskell does not specify an order of evaluation

Hmm... IMHO unsafePerformIO is 'unsafe' because it can lead to type
errors in runtime. At least, that seems to be much more dangerous.
Oh yes, quite right.
This and especially the wicked unsafeCoerce seem like great ways
to shoot myself in the foot and are strong candidates for inclusion
in entries to the International Obfuscated Haskell competition :)
