Consider the array
typeset -A b
b=("a b c" d)
The following correctly expands to "d"
${b[a b c]}
but this results in a "bad subscript" error:
$b[a b c]
I can't seem to find anything in the man page about why this would
be the case. It seems to be a parsing error, since using a separate
parameter to store the key works fine as well:
z="a b c"
print $b[$z]

Without the surrounding brace, the spaces separate words, so it looks at
"$b[a" and doesn't like it.
