Currently the variables set in our `foreach` handler live forever, potentially overwriting global variables with the same names. This pull-request will close #123 by handling scope for this case correctly: * The variable(s) set in the foreach statement will only live for the duration of their enclosing block. * This means they'll be unavailable when the block is terminated. * And this will work for (deeply) nested loop-iterations.
This is a combination of over-engineered and heuristic-based. Probably works.
