Is there any way to make the IO Monad lazy?
The simplified version of my problem is that I want to generate an infinite structure from an IOArray and then consume only the relevant part of it.
Yes, unsafeInterleaveIO.

This is how getContents is implemented so that it reads the file lazily.
Be careful of course it is "unsafe".
