Err, implicitly convertible to *mutable*. It goes both ways.
It does? Not according to my tests. And it would be bad if it
did, because the returned immutable value could actually
reside in read-only memory.
join returns a mutable array, that can be implicitly casted to
immutable if join is pure.
I'm talking about the general case. Jacob seems to be saying that
a unique _immutable_ value is implicitly convertible to mutable.
