Walter and I discussed the matter again today and we're on the brink of
deciding that cheap copy construction is to be assumed. This simplifies
the language and the library a great deal, and makes it perfectly good
for 95% of the cases. For a minority of types, code would need to go
through extra hoops (e.g. COW, refcounting) to be compliant.
A simple question: can a reference counter work with const and immutable?
const(S) func(ref const(S) s) {
return s; // this should increment the reference counter, but can we
bypass const?
}
Bypassing const/immutable could work, but if your data is immutable and
resides in read-only memory you'll get a crash.
