Brace expansion from arrays?

Brace expansion from arrays?

[Johann 'Myrkraverk' Oskarsson]

Hi,

Out of sheer curiosity, I was wondering if it was possible to brace
expand {stuff,to,expand}to from arrays too, that is

a=(stuff to expand)
print {$a}to

would output "stuffto toto expandto"

Prelimanary man page grepping and testing indicated: no.  So, is there
a way to get the same effects from array expansion? And, would
automagic brace expansion from arrays be 1) useful and 2) hard to
implement?

print ${^a}to

In that case, is it too much to ask to reference that in the chapter
about BRACE EXPANSION in the man page?

That is, would it make sense to have the following as the last
paragraph in it:

    See ${^spec} in PARAMETER EXPANSION for similar expansion of
    arrays.
