I don't think you said anything about which version of Hugs you are using. It might be irritating, but it shouldn't be too surprising that you will encounter problems if you try to use a recent release with a textbook that is, if I recall correctly, about five years old.
Well, 'fromInt' figures in Mr Pope's *Tour of the Haskell Prelude*, which dates, I believe from summer 2001; mention of it seems to have been removed from the account of Numeric library in November of the same year. http://www.haskell.org/definition/haskell98-bugs.html I find no evidence from the original Haskell 98 Report that 'fromInt' was ever part of the public interface, so this in fact appears to amount to a minor tidying up. Thompson's book is from 1998, before the report was published. If the author does indeed make use of this function in the book, perhaps this should be submitted to him as 'errata'. Alwyn
