Thanks for that work Joel. That is something useful to know. I like the way
your result encourages one to use a form that has the least effect on the
parent/calling expression
- whether you evaluate the condition early eg:
condition-result: dummy = 1
or you evaluate it late using the function:
condition-result: does [dummy = 1]
Your "parent expression" eg.
print condition-result
Need not change (unless of course dummy does). A nice finding.

Too often true! :^)
