I install it, I tried it, and it doesn't work for me.
Ambiguous type variable `a' in the constraint:
`Integral a' arising from use of `*^' at ./Hat/DML.hs:535:66-69
Probable fix: add a type signature that fixes these type variable(s)
And this is line 535....
T.uapp2 p125v94v125v148 p125v147v125v147 p (+^) (*^)
After that, I have in my code used operator ^, and I deleted that
operator. Program finally compiled, but now, hat-observe reports me an
error... this program has encountered a problem....
So, I will be really happy with something simple as Hugs.Observe if it
works with floats. Some recommendation please?
