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.
