# layout - kinda python-like.
# indents are multiples of 4 spaces, no tabs allowed, violations won't compile
# if something is indented from the line before, it's implied that it is part of
# the thing defined on the line before
# defining an interface
# when things are immutable, a property is no different to a no-arg function
