I don't understand the ambiguity. If param= "#obj[@]", then it

Stop there. In something like ${#obj[@]}, `param' is `obj[@]'. The
`${#param}' is a clearly-defined word expansion, separate from the
`[:]-' forms:

Please, I'm not running in posix mode, so how would their rules
apply? Just because pi=3 under Indiana state rules some number of years

doesn't mean it should apply in a non-posix mode shell.
