This proposal seems fairly uncontroversial at the moment. I would really like it if someone more familiar with the proposal process can take this proposal up and help make sure it gets in the next batch. I can't even figure out how to create a wiki page for the proposal right now :)
Well, this proposal seems uncontroversial because we didn't arrive to the difficult part: what operations should we define on this String type for it to be useful. Because with only this proposal as it stands now (String defined as an implementation-defined newtype, a typeclass defined for conversion from/to String and [Char] as an instance of this typeclass), we're in a worse situation than before: not only String became useless given there is no operations defined on it, the only mean we have to portably work with it is to translate it to [Char] before doing anything. So now, the fun part begins...what operations should String support ? I propose obtaining the length of a String, taking a substring of a given size beginning at a given index, taking the character at index i in a String, concatenation, converting a string to upper/lower case and determining if a string is contained in/a prefix/a suffix of another. I am sure I am forgetting some useful operations and some operations I said are better placed in the typeclass or in a typeclass instance or are particular cases of general operations we should define rather than the particular cases. So, what are the operations we should define according to you ?
