Boolean operators

Development
#1

Hey,

I have seen several times that it is recommended to use &&/|| for
boolean expressions, and/or for control flow. E.g.:

Use &&/|| for boolean expressions, and/or for control flow. (Rule of
thumb: If you have to use outer parentheses, you are using the wrong
operators.)

boolean expression

if some_condition && some_other_condition
do_something
end

control flow

document.saved? or document.save!

It is to prevent issues with precedence. Opinions?

ps - Do we have a style guide?
