Hi.
What are the available methods to execute IO actions from pure code?
I know only unsafePerformIO and foreign import (to call a non pure foreign function).
unsafeCoerce is a back door for almost everything.
The mueval tests also include this fun example: 'runST (unsafeIOToST (readFile "/etc/passwd"))' -- gwern http://www.gwern.net/
