Subject: Re: Why "and and or" Have Different Association from "&& and ||"?

Hi,

I tend to agree with Nat, that probably the "English influence" should be
diminished in this respect.  Well, in Perl there is some "use
English" module that will make "and" to replace "&&", etc., but there they
are perfectly equivalent.

In Ruby, I like that "and, or, not" have lower precedence than
the assignments, because in most my code, that is what I want to
accomplish (with assignment being the side-effect).  But now, we have to
put the extra parentheses if the "or" is on the left side of the
"and".  Doesn't this put an extra work on our brain, even for
English-speaking people, as in most other computer languages the
"and" (either in "and", "&&", or ".AND." forms) always has higher
precedence than the "or"?

Regards,

Bill
