Re: Make const, immutable, inout, and shared illegal as function attributes on the left-hand side of a function

[Martin Nowak via Digitalmars-d]

This has been being brought up for years. I wouldn't expect 6 
months to change
anything. If we want to delay it until dmd's headergen and ddoc 
are fixed and
put a note in the changelog on the next release that it's going 
to be
deprecated rather than deprecating it immediately, we can do 
that, but I don't
think for a second that the arguments are going to change.

Automatic code rewriting is what might make syntax deprecations 
more feasible in 6 month.
