Dan, can you suggest any words we could add to the documentation that would have prevented you stumbling?

I guess the thing that would have helped best would have been an error message like "'x' not in scope, use -fforce-recomp to see all symbols" when running interactively in ghci with a previously compiled top level module.

FWIW, I'm thinking the right thing to do is -fforce-recomp explicitly loaded (:l) modules by default, with documentation specifying to -fno- force-recomp if you don't want that for some reason. If you're using ghci, most of the time you *don't* want the normal ghc symbol behavior. (The above would still be useful, if you then switched to a module pulled in by the explicitly loaaded one and tried to work with a non- exported symbol. I do that a fair bit when developing/debugging.) -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
