Range creating operator

This group of binary operators is used to create ranges. The two operands define the left and right edges of the range. The presence of the ^ character indicates that the corresponding edge is open; thus, it does not include the given number.

Run the following example to see how it works:

.say for 1 .. 5;   # Prints the numbers: 1, 2, 3, 4, 5.say for 1 ..^ 5;  # 1, 2, 3, 4.say for 1 ^.. 5;  # 2, 3, 4, 5.say for 1 ^..^ 5; # 2, 3, 4

You may choose your own style regarding the spaces around the operators. So, both 1..^5 and 1 ..^ 5 are acceptable. However, it is not possible to insert a space between the characters of the operator, such as 1 .. ^5.
