Here's something I wrote up on const:
So as to the main thrust, I generally agree. In fact, I think const is almost useless even if you want to use it fully: you said immutable is better in many places, and yes, but in addition to that, inout is better than const in most the remaining cases.
Constructing a const variable? Almost completely useless - immutable is better in almost all (if not actually all) cases. Referencing function parameters? inout is better in all cases except just plain input. If there's any part of it being returned - as is the case on most member methods to me at least - inout is flat-out better.
And then, of course, like you said "don't use it" is the solution to most of the const system's flaws anyway.... which seems to be the case with a lot of D's add-on qualifiers.
