Array Assignment Operators

Arithmetic may also be performed on arrays. These operations can be SIMD-accelerated.

• Add: +=
• Subtract: -=
• Divide: /=
• Integer Divide: //=
• Multiply: *=
• Exponent: **=

There are also some array-specific operations:

• Append (++): Append values to the array

$ let ARRAY = [ 1 2 3 ]
$ let ARRAY ++= 4
$ let ARRAY ++= [5 6 7]
$ echo @ARRAY
1 2 3 4 5 6 7

• Append-Head (::): Insert values at the beginning of the array

$ let ARRAY = [ 4 5 6 ]
$ let ARRAY ::= [ 1 2 3 ]
$ echo @ARRAY
1 2 3 4 5 6

• Difference (\\): Retain values which are different from the array on the right

$ let ARRAY = [ 1 2 3 4 5 6 ]
$ let ARRAY \\= [1 3 5]
$ echo @ARRAY
2 4 6
