One of the main complaints of a binary operator in PEP 3101 was the inability to mix named and unnamed arguments:
The current practice is to use either a dictionary or a tuple as the second argument, but as many people have commented ... this lacks flexibility.
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. Steve -- Where did you get the preposterous hypothesis?
