I believed that the location that matters, in this case, was only the
object instantiation (program/implementation body), because it was, in
both cases, after the helper declaration. A little weird.
No. Whenever you call a method (either inside a class using (implicit)
Self or outside using a variable) the compiler checks whether a helper
for that type is in scope and uses that if it is. It has nothing to do
with object instantiation (that would be more for Traits/Mixins:
http://en.wikipedia.org/wiki/Trait_%28computer_programming%29 ).
