What is the relationship to OverloadedStrings? Since "blah" is sugar for ['b','l','a','h'], could OverloadedLists also work for string literals / string patterns?
It's described in the wiki. OverloadedLists could subsume OverloadedStrings if the former had an statically allocated compact representation for certain lists, which we have for Strings today (see unpackCString#).
