A way around this, which may be the same as the approach used by string was:
alias immutable(Msg_) Msg;
class Msg_
{ ...
This so far appears to do what I want. The only problem is that it
introduces an extraneous symbol, which I would prefer to avoid.
OTOH, I did fix a few problems before this solution

This is surely possible, because string acts just that way, but I
can't figure out how to do this.
immutable class Msg { this(...) immutable{...} ... }
doesn't work that way, as when I do
Msg m = new Msg (...);
I get:
Error: incompatible types for ((this.m) - (m)): 'immutable(Msg)' and
'cellram.Msg'
and
Error: immutable method cellram.Msg.this is not callable using a
mutable object
Does anyone know the correct approach?
