Since toHash() cannot be overridden in an immutable class,
is there a work-around?
Kind of, but I don't thi
But think about if enforced immutability is really what you
want.
You don't need to mark the fields immutable to be able to
construct immutable Xs. A `pure` constructor is handy, as it can
construct both mutable and immutable objects.
class X
{
private int x;
this(int x) pure { this.

In other words,

What's concatenation by juxtaposition?
When "foo" "bar" turns into "foobar". The two string literals are
right next to each other, no operator or anything else in
between, so they are combined.
