OK, the Word module has been fixed in the repository, but not the Int
module. Hmmm, looking at the sources, I don't understand the reason why
the IntXY methods for fromInteger use a case while the corresponding
methods in Word don't:
Int.lhs:
[...]
fromInteger (J# s# d#)
= case (integer2Int# s# d#) of { i# -> I8# (intToInt8# i#) }
[...]
Word.lhs:
[...]
fromInteger (J# s# d#) = W8# (wordToWord8# (integer2Word# s# d#))
[...]
Are the XtoY# functions lazy?
Cheers,
Sven
