isAlphanum

Dear Hugs Maintainers, I would like to ask if it is done for purpose that the function isAlpnanum is called isAlphaNum in Hugs. Here is what the February 2001 version of Hugs tells us: Prelude> :t isAlphanum ERROR - Undefined variable "isAlphanum" Prelude> :t isAlphaNum isAlphaNum :: Char -> Bool The report on the library Char says that the function should be called isAplhanum. Also, Hugs manual mentions it in that form. Various libraries, like Regexp, rely on this statement and one has to manipulate their sources to get them work with Hugs. I would also like to ask when the library Directory is expected to be included into Hugs' distribution. Best Regards, Rysiek
