Yes Hugs has a option "+s" but it counts some sort of reductions not exactly the beta reductions.
Thanks.

Hugs has, afaik, a "output reduction count" option somewhere. At least it had one the last time I used it.

I heard that a Gofer compiler (a Haskell dialect) supports counting the Beta
reductions.
Hence I thought GHC/Hugs would have a similar facility.

GHC-compiled code is so fast is that it turns into straight-line code
whenever possible, via inlining, primitive optimizations, etc.

Thanks.
