The other reason an operator was a pain is the order of operations:
>>> '{0}'.format(1 + 2)
'3'
>>> '%s' % 1 + 2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
In general, I don't see any gain in introducing an operator for string
formatting. What's the point? Maybe you save a few characters of
typing, but it sure is easier to Google for "Python string format"
than for "Python @".
A big -1 from me.
