Is there any wisdom behind “and”, “or” operators in Ruby?

Question

I wonder why ruby give and, or less precedence than &&, || , and assign operator? Is there any reason?

Answer 1

Being able to control the precedence of your operators is sometimes useful, especially if you are concerned with readability -- extra parenthesis in conditional statements can sometimes obscure the actual logic.

To be frank, though, I think the reason Ruby has the boolean operator precedence levels it does stems mostly from the fact that Matz was a Perl programmer before he ever wrote Ruby, and borrowed much of the core syntax and operators from that language.
