Type error message pretty-prints unboxed tuples wrongly
I get
PASysDep.hs:51:
Couldn't match
`(State# s, MutableByteArray# s)'
against
`(State# t, MutableByteArray# t)'
Expected type: (State# s, MutableByteArray# s)
Inferred type: (State# t, MutableByteArray# t)
In the application `newByteArray# (wORD_SCALE n#) s#'
In the right-hand side of an equation for `newIntArray#':
newByteArray# (wORD_SCALE n#) s#
where the actual error is that I have used boxed instead of unboxed tuples in a type signature. In other words, the inferred type should have been reported as
(# State# t, MutableByteArray# t #)
The code producing this error is as follows:
import PrelByteArr (cHAR_SCALE, wORD_SCALE, fLOAT_SCALE, dOUBLE_SCALE)
import PrelGHC
newIntArray# :: Int# -> State# s -> (State# s, MutableByteArray# s)
newIntArray# n# s# = newByteArray# (wORD_SCALE n#) s#
