Please omit at least "Of" from XxxxOf, or what was the intention of "Of"? In Map this leads to a name "isProperSubsetOfBy" and apart form this "Subset" should become "Submap" within Map!

So it is agreed: we use "isXXXX" :-) I am not sure about "XXXXOf" -- my taste says leave it out, but I once added it as it seems more consistent. I guess "submap" covers the meaning better than "subset" in the case of Map's. -- Daan. ps. I have a general remark towards nice cozy names like "subset", and "null", versus consistent COBOL names like "isSubsetOf" and "isEmpty", I believe that we should target an audience that sporadically uses the library and those people must be able to guess names -- the lenght of the name is not so important in that case, especially not for rarely used operations like "isProperSubsetOf". A hard-core user can always define "null = isEmpty; psubset = isProperSubsetOf" at the start of his module. (and I feel that "null" should be reserved for lists)

does "isIn" meet someone's taste for "member" then? (I would not like "isMemberOf") Christian

the list module is not very consistent in the naming, so while it may be nice to be compatable with it, i woun't go too far with that.

I expect most haskellers to know the List module inside out. So they'll propably be confortable with something very close to it. Additionally, lists cannot be discarded, so we'll have to keep the list module. Having to remember two sets of conventions would not please me.

for example, names like "null" and "nub" could probably be improved.

If anything has to be improved, let it be the list module, and the rest would follow. Cheers, JP. __________________________________ Do you Yahoo!? Yahoo! Mail - More reliable, more storage, less spam http://mail.yahoo.com
