More assignment operators

var %x += 10 (var %x = %x + 10)
var %x -= 10 (var %x = %x - 10)
var %x *= 10 (var %x = %x * 10)
var %x /= 10 (var %x = %x / 10)
var %x ^= 10 (var %x = %x ^ 10)

These would preferably also work if you don't use the /var command.

totally agreed

in addtion:
var %x = 10
var %x += hello
//echo -a %a = 10hello

would be nice if it concatenated, if either the assigned string or the added string is not numeric.

I think these would be very useful:

+= add
-= subtract
/= divide
%= modulus
*= multiply
.= concatenate
