Even so you have to modulus a tuple or a variable. That doesn't make any
more sense for a newbie and is just as inconvenient for the script
kiddie (which is often me!), compared to languages like Perl, Ruby, Tcl,
sh etc.

Python's interpolation syntax is: more verbose, more complicated, less
secure and also more powerful. I have no problem with keeping the power
but I'd like something less verbose and less complicated alongside it.

I don't believe that this feature should be taken away from you. But I
don't see how it relates to the PEP because what you want to do is
already doable. PEP 215 is about making things *easier for simple
cases*. If you have new, high-end needs for runtime string interpolation
then PEP 215 probably won't address them.
