Then how about this: words inside a compound assignment statement that are
recognized as assignment statements ([1]=foo) are expanded like assignment
statements (no brace expansion, globbing, or word splitting). Other words
undergo all the expansions.
That means you can do things like
[{0,1,2,3}]=foo
to set the first four elements to the same value, but things like
f='more than one word'
x=( [0]=$f )
will still only set the first element. This sounds like what you're after.
