Subject: Re: readable and provocative & daring

&& and 'and' both exhibit the same behaviour, in that they short-circuit.

& is a combiner-and, not logical (rather, typically bitwise), which
requires it evaluate both sides of the expression.

Maybe you really wanted:  readable and provocative && daring

Yes, of course, you can make your own versions, but you need to keep
this behaviour in mind.


def foo
  p "foo"
  false
end

foo && foo
> "foo"

foo || foo
> "foo"
> "foo"

foo & foo
> "foo"
> "foo"

foo and foo
> "foo"
