For the array function, the 1-argument case (which is equivalent to the 
1-line "y[] = ..." form) is special - because it needs to break its 
argument into pieces along the whitespace, it has to evaluate it eagerly.

Use

y = $(array $`x, 1, 2, 3)

or, equivalently

y[] =
   $`x
   1
   2
   3

or

y[] =
    $`x

y[] += 1 2 3
