[Haskell-cafe] Stupid newbie question of the day: why is newMVar in the IO monad?

[Felipe Lessa]

There are at least two packages on Hackage that try to solve this
problem once and for all:

  http://hackage.haskell.org/package/global-variables
  http://hackage.haskell.org/package/safe-globals

Note that, for "global-variables", you may use an unexported newtype and
an empty string if just using a global string smells bad for you.

Cheers,

Felipe.
