Are you sure?  I'm pretty sure Argument Clinic signatures support 
"return converters", which are emitted in the text signature as a return 
annotation.  See the section "Using a return converter" in 
Doc/howto/clinic.rst.

What appears to be lacking is a "return converter" that handles 
strings.  I don't know how easy or hard it would be to write one--I 
haven't thought about Argument Clinic in years.  However, the 
DecodeFSDefault() returns a string type, with some extra implied 
constraints on the value I think.  So my guess is, it wouldn't be too 
hard to add a simple "str" return converter.


Cheers,
