Both arrays and hashes probably warrant something. I understood 'clamp' on
p5p in verb context, but would rather see something a little more
descriptive as an adjective.
I was originally thinking 'fixed', but that makes the distinction between
changable and non-changeable internal values nebious - which is constant and
which is fixed?
I then thought about 'resizable' That wouldn't allow the addition or
deletion of keys (or indices), but would allow the internal values to be
changed.
Today, I don't particularly care anymore.
In any case, properties will be pushed to the bottom of my stack for things
to document. There's a lot of Perl 6 contending for the bottom position, it
seems.
