EIBTI, it's true, but in some cases it's awfully handy to be implicit.
Ian Bicking and I were tossing this around, and came up with some
ideas, all of which are certainly flawed in one way or another :)
One idea is that an additional string formatting method which will
automatically work with locals() and globals() could be named
something like "eval". On first glance, this seems like a bad name
because of the builtin eval() function, but perhaps it would be a good
thing. People are warned off using eval() on strings they didn't
generate, and the same should be true of a string eval() method, for
the same reasons. (Or as a few of us have noted: "eval" == "evil")
In any case, the initial C implementation of PEP 3101 automagically
does this if format() has no parameters, but that is easy enough to
rip out.
