Until Python 2.5, the \keyword{try} statement came in two
flavours. You could use a \keyword{finally} block to ensure that code
is always executed, or a number of \keyword{except} blocks to catch an
exception. You couldn't combine both \keyword{except} blocks and a
is always executed, or one or more \keyword{except} blocks to catch
specific exceptions. You couldn't combine both \keyword{except} blocks and a
\keyword{finally} block, because generating the right bytecode for the
combined version was complicated and it wasn't clear what the
semantics of the combined should be.
