Actually, the first is not an array assignment; there is nothing
syntactically special about the parentheses in a typeset statement.
(In fact, it does grouping in all statements, to make globs using
parentheses work sensibly, which is why the spaces don't separate words,
but even so typeset just gets the string `x=(a b c)').  You should find
x contains the string '(a b c)'.

As the outer (...) is not special, the $(cat file) splits the thing
into three arguments: x=(a, b and c).  typeset complains about the last
one.

The fix is to do `typeset x' first, then the array assignment to x in
a separate statement.
