More directly, (1,2,3) will interpolate in list context, while
[1,2,3] will not.
say (1, 2, (3, 4, 5)).elems # 5
say (1, 2, [3, 4, 5]).elems # 3
The first example has a List containing five Ints, the second example
has a List containing two Ints and an Array.
It's also useful to consider the difference between:
$x = (3); # $x becomes an Int
$x = [3]; # $x becomes an Array
