Hi,
In general, when working in the IO monad, it guarentees that the order of
operations is the same as how it's specified. For instance:
main =
do putStrLn "hi"
putStrLn "bye"
could not possibly output "bye" before "hi".
What if I don't care about this? Is there any way to tell the compiler
that it is free to reorder these?
The reason I ask is that I'm generating a FSM description file and it
doesn't matter which order I list the transitions in. I'm curious whether
I could get the program to run any faster if I don't care about order.
The only thing I can think of would be to define a new nonsequential IO
monad that basically used unsafePerformIO to do the computations. So it
would basically transform the above from to:
main =
unsafePerformIO (putStrLn "hi") `seq`
unsafePerformIO (putStrLn "bye")
and then order wouldn't be guarentee, right?
