Oh, forgot to mention in the last email: it's sometimes wasteful of
resources or just really inconvenient to do this if this repeated
block of code relies on lots of locally scoped variables. With
literate programming, you can include the same block of code in
multiple locations without defining a function. Go look!

Old debate. See for example, for the opposing view, D.E. Knuth,
"Structured programming with goto statements", Computing Surveys 6
(December 1974), pp 261--301. Reprinted in D.E. Knuth, Literate
Programming, CSLI Lecture Notes. I guess similar arguments would
apply to returns as well. Of course, if you document what you are
doing very well, and use these constructs with care, then it doesn't
