fwiw, I'm not so sure about "insufficiently questioned". lots of
post-Pascal SP work fully support your view. see e.g:
"Loop Exits and Structured Programming", by Eric Roberts:
http://www.seas.smu.edu/~kornerup/cse1341/robertsfiles/documents/loopexit.txt
"At all levels of experience, students using [a version of pascal
supporting internal loop exits] were more likely to write correct
programs than were their counterparts in the control group"
in python 3000, expect "while" to be replaced with "loop/if/break" ;-)
Cheers /F
