I would avoid that. Without looking at your whole code I can't really say the
right way to do that. However, I recommend you take a look at devise. It's a
little top-heavy but it's worth it once you get the hang of it. Also, if you
don't want to actually use it, read the source code and see how they do it with
password validation.

You're right -- they are equivalent in Ruby 2.0 (and to make matters worse I
actually switched between Ruby 1 and Ruby 2 syntax in the same line of code).
Probably best to stick with the shorthand if you're using Ruby 2.
