       Just spent 20 minutes pulling my hair out because Ruby's "and" has lower operator precedence than assignment to variable!#programming #nerdy #ruby

       @LukeAlmighty Yeah, but my life so far hasn't prepared me for the possibility that "x = a and b" is not "x = (a and b)" but instead "(x=a) and b".

       @dusoft That should serve as a lesson in difference between "and" and "&&"...

       @fuxoft Yeah, 20 minutes is an insane speed when it comes to this bullshit.

       @fuxoft That's how the rule of thumb "and/or only for control flow" came to be: "a<b && b<c" versus "perform(action) and log(action)" (with the latter being synonymous to "log(action) if perform(action)" in a more natural order).

       @fuxoft Also languages should be designed around common sense 🙂

       @fuxoft I hate that too. and/or in ruby are not logical and/or but logical composition. Point of their existence is to be able to express control flow in an expression.

       @dusoft In Ruby, assignments are expressions and "and" & "or" are intended for composing larger expressions while "&&" & "||" are intended for "normal" boolean operations. I can't say I approve but it makes some sense.
