-1. 

Too dangerous. If string interpolation makes it into the core,
then please use a *new* construct. '\$' is currently interpreted
as '\$' and this should not be changed (heck, just think what would
happen to all the shell script snippets encoded in Python strings).
 
BTW, why don't you wrap all this interpolation stuff into
a module and then call a function to have it apply all the
magic you want. If I remember correctly, someone
else has already written such a module for Python.
