It would make it possible to share code like this across py2 and py3:
a = u'foo' Instead of (with e.g. six): a = u('foo') Or: from future import unicodeliterals a = 'foo' I recognize that the last option is probably the way "its meant to be done", but in reality it's just more practical to not fail when literal notation is more specific than strictly necessary.
You are giving these two options already:
- The former works for all Python versions. Although it may appear tedious to convert existing code to replace all Unicode literals with function calls, it would actually be possible/easy to write an automatic converter that does so for a complete code base, based on lib2to3.
- the second version is truly practical for all applications/libraries that only support 2.6+.
In addition, there also is another option:
- use 2to3, in some form
So you have already three solutions which are all transitional in some sense, and you want yet another option? I fail to see why this option is more practical than the options that are already there.
