It happens, though -- for code whose performance is not important,
e.g. initialization and "resetting" kind of stuff, a PyRun_String can be
SO much more concise and handier than meticulous expansion of
basically the same things into tens of lines of C code... since
"messing from the outside" happens after initialization, and the use
cases I can easily find are all specifically DURING initialization, it may
be that this problem is too rare to worry about, but, I'm not so sure.
