"Well, exceptions IMO do seem to be a bit unstructured in that control
is immediately transferred to another block and everything is surpassed
so that the possible paths of execution may not be obvious, however
I think this is a very small price to pay for such a beautiful way of
handling errors."

This is an odd definition of structure, but if this is your definition
of structured, then I think your assumption that anything that is not
structured is bad is wrong. I know you go on to say that exceptions are
useful, but you should not accept even for a moment the orhodoxy that
such transfers of control are somehow unstructured and therefore inherently
bad! I assume you have read Knuth's paper :-)
