I'm rather partial to label/leave construct. It is the
only construct I'm aware of that allows an exit from
two loop levels without resorting to a dispicable "goto"
(oh, it hurts even to type it in quotes).

As far as I know, there isn't an accepted syntax for
labeled blocks. The obvious candidate is:

statement := <label> : <statement>
label := <identifier>
