Hi,
the problem (already solved in Rebol/View) is, that Switch is a
function, which executes the Return in question. You can see its
source code by executing:
source switch
If you would do the same code in Rebol/View, you would experience
one attribute in Switch definition - [throw], which is essentially
an instruction for Switch to tell the calling function Return has
been evaluated.
