[Haskell-cafe] Getting some funny brackets in Haddock docs

[Steven Leiva]

I consider myself a Haskell beginner, and I think that the current
situation (with the use of *fromList*) will be less confusing than the
funny brackets.

Even if you could make it so that copy/past would turn funny brackets into
fromList, it would still be surprising behavior. When the code does
something unexpected, we are going to try to put in the funny brackets in
the repl. (Maybe that's more for programming beginners versus Haskell
beginners, but let's not discount them either).

I haven't read the docs, and I understand that your primary concern is the
noise from *fromList*, but I think leaving things as is and adding some
wording that says "Hey, if you want to avoid having *fromList* everywhere
in your own code, you can add OverloadedList  extension" would be the most
approachable. (Shouldn't be too much to ask a beginner to at least read the
preamble of a module's docs).

Just my 2 cents.
