Would it be useful to have one Python source file with an OrderedDict of
(API_feat_lbl, [(start, None)]) mappings
and a lookup?
* [ ] feat/version segments/rays map
* [ ] .lookup("print[_function]")
Syntax ideas:
* has("print[_function]")
Advantages
* More pythonic to check for features than capabilities
* Forward maintainability
Disadvantages:
*
Alternatives:
* six, nine, future
* try/import ENOENT
