I upgraded from GHC 6.6.1 to 6.8.1 and around that time I noticed that
the output from an app I am working on changed. I have distilled the
code down to the following example that produces different output
depending on whether it is compiled with -O2 or not:

Thanks for the feedback. Unfortunatly the Space Invaders game uses HGL,
which is not supported on Windows anymore. Is it supported on Linux?
Frag does compile and run on Windows using GHC 6.6.1, so that might be a

Moreover, functional programming makes it easy to have much more state than
imperative programming, namely state over *continuous* time. The temporally
discrete time imposed by the imperative model is pretty puny in comparison.
Continuous (or "resolution-independent") time has the same advantages
Hi,
I would like to get a string for a number
using always 2 digits (i.e., 75 would be
"75", 3 would became "03"). What is the
best way to do that? I tried

which gives me the correct string, but
ghci always ends that call with a
*** Exception: Prelude.undefined

Prelude Text.Printf> printf "%02d\n" 3 :: IO ()
03
