Well remembered, thanks.

It could also do with some tests, I've attached some.

I would like to use SyntaxException instead of ExitException for
all cases where an error can be detected at compile time
in a style file.

I realise that ExitException was already used in that class.
PartFilter is the only other example I can see where it does
not use SyntaxException.
