By the way, I hope it's possible to make the assignment `$x = 3` to
the read-only variable $x a compile-time error.
In fact, I hope this to such a degree that I would like it to be part
of a spec somewhere that a conforming Perl 6 compiler disallows
assignments to read-only variables. I find nothing to this effect in
S04 (but my grep-fu is imperfect, so I may just have missed it).
Pugs currently dies with a run-time error on this. Rakudo r27392 runs
it fine and sets $x = 3 as if $x wasn't read-only.
