On: Glom – Restructured Data for Python

They’re pretty comparable when the strings are constants. The fun begins when the string is dynamically created.

I wouldn't recommend dynamically generating strings. Strings are just a shorthand for Path objects, use Path instead: http://glom.readthedocs.io/en/latest/api.html#specifier-type...

I definitely wouldn't recommend it either. Sorry not to be clear.

In my experience, it's almost impossible to dissuade people from generating strings if the API affords it. We can't even stop people from generating SQL by concatenation!

Musing: does Python have a way (Mypy?) to declare that a method can accept only constant expressions?
