Subject: Best practice for &&, ||, and, or

Hi group,

I really would be interested in your thoughts about this

   a. in the context of your own projects, and
   b. with regard to teaching programming newbies

The GitHub Ruby Styleguide [1] states: "The and and or keywords are 
banned. It's just not worth it. Always use && and || instead".

So what's your practice/recommendation:

   1. use only &&, ||
   2. use only `and', `or'
   3. distinguish between boolean expressions (if this && that)
      and control flow (loot = give_money  or die)
   4. ???

1. and 2. might require extra parentheses that often could be
avoided with 3., but using parentheses might be clearer anyway.
Especially for students who might have a hard time coping with
the different precedences.

I tend to 1., and for own projects maybe to 3.

Regards,
Marcus
