Yes, it absolutely does.  My apologies.

Amusingly enough, I don't have to deal with serializing dicts.  :) 
However, as a comparison:  imagine you had to transform your dict to 
JSON every time some function wanted a dict as input.  And had to 
transform returned JSON strings in to dicts.

I don't follow.  When dealing with the file system one passes a string* 
representing the path of the object one wants -- pretty much the same 
string that was passed in to Path.


* or bytes, but the same sameness, really.
