I sent Philip a patch last month that adds expansion items as alternatives
to ${hash_ ${length_ ${nhash_ and ${substr_ so that the underscore-separated
numeric parameters could instead be written inside braces and subject to
expansion. I didn't do this for ${quote_ -- I'd be interested if anyone
could think of a good reason for expanding the argument in that case :-)
