That is indeed an interesting read.

Thank you for sharing your patch. I like it, though I think some of the
iteration controls are hard to read - especially the ones that perform a
'continue' operation. With time I'm sure I would grow more comfortable
with them. I'd prefer 'break when' and 'continue when'. The 'when'
keyword could then be used to support a 'case' statement implementation.
And now we're off on another grand exploration!
I have downloaded your patch but I do not think I will be trying it
anytime soon. I haven't even installed 5.1 yet. That might happen soon
now that a feature freeze seems to be in the works.
Doug
