G'day Erik,
I'm struggling to imagine any cases this would be useful excepting do-while
loops (which exist anyway). I'm also not entirely convinced the loss of
readability (if the first hunk of code was really big, I wouldn't know to look
for a butfirst block and might therefore misunderstand the code) would make it
practical.
Can you give some pared down examples of what kinds of things you'd put in each
block and in particular why you wouldn't just do the butfirst stuff before the
first block?
All the best,
Jainta
