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.

As Timon said, this won't make the grammar context dependent.
Also,
C# has the concept of contextual keywords. Such keywords have
special meaning in certain contexts but are otherwise available
for use as identifiers. C# also allows to use normal keywords as
identifiers, but you have use the @for syntax to disambiguate
(e.g. see http://rextester.com/JBOTC21251). From my experience of
using C# the system is well designed and I have never seen
problems in practice. I'm sure something similar can successfully
be implemented for D. Though I would consider such enhancement
with low priority.
