[Haskell] Annoying naming clashes

[Ben.Yu at combined.com]

Tom,
Then what will you do when naming operations in a class? Is it right that
care has to be taken in order not to conflict with other classes?

Say, I have a Person class where I want to define an operation "getName".
Is it wise to name it "getPersonName" instead?

I notice that FiniteMap always names operations and functions xxxFM,
although that looks ugly to me. Is that a general good thing to do when
naming operations?

Ben.

Hi.

Try using small modules and qualified names.

    module Illumination where
    data Illumination = Dark | Light

    module Weight where
    data Weight = Heavy | Light

    module UseBoth where
    import Illumination
    import Weight
    easyToCarry = (Illumination.Light, Weight.Light)

Regards,
Tom
