# There's no such thing as scalars in Ruby. Which is a blessing, because
# figuring out what kind of variable you have is annoying. In Ruby, x is a Fixnum

# true stuff here
# false stuff here
# a lot of ruby stuff has end at the end, some things will actually take braces
# {

# parens() unless the language can't figure out which order you mean. Let's
# talk about that.
