This would create work we don't need.

Solution: __str_shell_ escapes, adds slashes, and quotes. __str__SQL__ refs a global list of reserved words.

I don't understand why % and .format got interjected into this.

If you are mentioning them as 'get the unprocessed version of any string formatting', that is a bad idea, and not needed, since you already have an unprocessed string object.  Assuming the method were named "hypothetical":

>>> 'foo bar'.hypothetical()      # returns 'foo bar'
>>> '{0} bar'.format('foo').hypothetical()      # returns 'foo bar'
>>> ('%s bar' % ('foo',)).hypothetical()     # returns 'foo bar'
>>> f'{foo} bar'.hypothetical()     # returns '{foo} bar', prime for translation.

could gettext not be modified to create the same AST as f'{foo} bar' when it is translated to '{foo} le bar.' and inject it back into the runtime?
