Variable scope

RimStone uses scope rules for variables that are similar to other programming languages. Variables are defined within code-blocks and their scope is determined by such blocks.

Note that a variable with the same name will not be defined again in a sub-block (see code-blocks); rather the same variable will be used. Of course, variable with the same name in two separate blocks (i.e. not nested and within separate code blocks) will be indeed separate variables.
