My objection wasn't to the use of strings, or the use of functions, only to 
encouraging the proliferation of alternate forms, cheap shortcuts, and/or 
underspecified transformations.

I do suggest that functions such as "isAbsolute(path)" be used, rather than 
proliferating ".startswith('/')" code.  When someone reads 
".startswith('/')", all they know is that the string starts with a 
slash.  If they read "isAbsolute(path)", they know it's an absolute path 
and can go look at isAbsolute() if they want to know how to spell an 
absolute path.
