codecs.escape_decode does not appear in the codecs documentation. This function is to my knowledge the only convenient way to process the escaped characters in a literal string (actually found here https://stackoverflow.com/questions/4020539/process-escape-sequences-in-a-string-in-python). It is most useful when implementing a parser for a language extending python semantic while retaining python processing of string (cf https://github.com/MatthieuDartiailh/enaml).

Is there a reason for that function not being documented ?
