Then, a continue could be written like here:
while cond do
I would far rather have a real, explicitly named continue that applied
to the "do" of the loop itself.
while cond do :process:
-- some processing
if somecondition then
break :process: -- stop all processing - break out of the loop the label mentions
elseif someothercondition then
continue :process: -- resume control of loop where "cond" is checked
-- other processing
In other words, if the label is a requirement of having an actual continue functionality, then I'd put up with that.
But of course, for the above case of continue, the "label" being literally the place where execution would first take place
after a continue would not be correct.
I don't see offhand why an unlabeled loop can't also "continue" if a labeled one could.
I assume this runs into the basic objection to "continue" that has always existed (i.e. where execution next takes place).
