hi,
in ghc-2.09 (solaris) i cannot use runST with LazyST
observe:
-------------------------------------------------------------
STRICT
$ ghc strict.hs
ghc: module version changed to 1; reason: no old .hi file
paratha$ cat strict.hs
import ST
main = print $ f True
f x = runST(
do n <- newSTRef x
readSTRef n
)
-------------------------------------------------------------
LAZY
$ ghc lazy.hs
lazy.hs:7: Value not in scope: `runST'
Compilation had errors
$ cat lazy.hs
import LazyST
main = print $ f True
f x = runST(
do n <- newSTRef x
readSTRef n
)
