ghci also accepts a number of other things.
You can define data types, type synonyms, classes, instances, so pattern
synonyms would seem to fall into scope.

Hey all,I was trying to define some pattern synonyms in ghci recently,
and that doesnt seem to work. Is that something slated to be fix in 7.10 or something?
I thought GHCi accepts things that would be valid in a 'do' section? So e.g.
x = ()
doesn't work in GHCi, but
let x = ()
does.
Pattern synonyms don't work for the exact same reason: they are not valid inside a 'do' block. _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
