So I'm not sure how that compiles for you.
I think that he's looking for a language change that would allow you to use
keywords in contexts where the keyword would not be valid. It's been
suggested before, but it was rejected. If nothing else, it doesn't at all
play nicely with how lexers and parsers normally work. It's _far_ cleaner if
the compiler can treat a keyword as a keyword in all contexts that it's
used. Not doing so makes the grammar context-dependent, whereas Walter has
gone to great lengths to make it completely context-free.

No, this would not introduce any context-dependence.

That doesn't mean it is necessarily a great idea though.
It increases ambiguity of the grammar, and hence, if you want to be able
to parse things like
auto enum = 3;
enum +=2;
then not-entirely-trivial disambiguation has to be added to the parser.
There's no ambiguity for the example in the OP though.
