That's correct.  I did bump into the limitation while designing a program a
couple of years ago, in the sense that I discovered it and worked around it.
(I don't recall exactly what the workaround was--maybe I switched to C++ for
that program.)

This would kind of work.  It doesn't seem like you could pass such a string as
an argument to re.match or re.sub or as an operand to 'in', though, and expect
things to work correctly.

Anyway, I was just curious about the status of this.  Thanks!
