I disagree. Nothing is being faked. The generic loop is
while True:
pre_process
if condition: break
post_process
If there is no pre_process, abbreviate the first two lines as 'while
condition:'. If there is no post_process, some would like another
abbreviation. Understanable. But the use cases seem relatively few. And
anyway, a competant programmer must understand the generic loop and a
fraction form, which I believe is at least as common as the no post_process
case.
