Do you think 'read' (actually, 'readsPrec'?) could be made to also read the international convention (ie., read "1,5" would also work besides read "1.5")?

IMAO, it's bloody well stupid to use commas for either the decimal separator or the thousands separator, as it has a well established role in separating the items in a list that conflicts with this. (...)
After 10 years of professional experience, I'm getting used to the fact that almost every time someone says my idea is stupid I'm going in the right direction. Linux, firefox… And know everybody in the office uses nothing else. "It's stupid to use anything but Java, that's what the whole world is using", and here I am writing software in Haskell. Really, no troll intended. This is an open source world, I'll try my own Read and Show classes. If others like it, great, if not, I was wrong in the first place :) Best! Thanks for your attention, Maurício
