[REBOL] Re: curious use of LENGTH?

Hi Joel,
<<
If any numeric value counts as TRUE, then
if length? s [print s]
and
print s
do exactly the same thing, since the IF would always be satisfied!
Hence my question, why the IF ?
>>
I'd say it shouldn't be there, provided they intended to print just a
newline (in which case I hope it's commented that way. Bummer that we can't
see comments for mezzanine functions.).
If they intended it not to print 0 length strings, they need to change the
condition to reflect that.
Probably worth a submission to feedback, unless they jump in here. It might
be that the same thing occurs other places in their code as well.
