Ah, errors, there are some many of them and so many ways to get them!
The [do] clause is optional. It is perfectly legal to do something
like:
while f(read())
So there isn't isn't really due to the missing 'do', but something
following the while is confusing the automatic semi-colon insertion
code. (It's easily confused, poor thing.) That's what makes error
messaging so hard - there are 'likely' reasons for an error and then
the 'real' reason - and sometimes fixing a likely problem can fix
the real problem - but sometimes not.
If you can share the next few lines following the while, maybe I
(or someone more into syntax rules!) can more precisely explain
what the real error was.
