Agreed, and it's sometimes confusing. I don't see "string % tuple" as
a good syntax; I prefer to spell it sprintf("format",arg,arg,arg).
When it comes to operators on strings, what I'd prefer to see is
something that does more-or-less what the operator does with integers
- for instance:
"This is a string" / " " ==> ["This","is","a","string"]
Taking a string modulo a tuple doesn't make any sense in itself, so it
CAN be given an alternative meaning. But if you see that in a program
and aren't sufficiently familiar with %s formatting to recognize it,
how are you going to locate the documentation on the subject? Googling
for 'python % string' doesn't help; 'python string modulo' brings up
an article on informit.com that explains the matter, but nothing
official. By contrast, searching for 'c sprintf' brings up heaps of
useful links, because 'sprintf' is a searchable keyword.
On the flip side, operator-based notations end up a lot more compact.
I'd definitely not want to give up, for instance, list comprehension
syntax. Difficulty of searching for docs is a downside, but definitely
not a blocker.
