Ruby 2.1 has a pretty nice new feature:
def sample puts "sample" end # => :sample
Method declaration returns the symbol for that method.
However, class or module declarations still return the value of the last expression. Most of these last expressions are methods. So, class/module declarations now return the symbol of some method within them.
class Sample def hello puts "Hello" end end #=> :hello
Previous versions of ruby returned
nil because the method declarations returned
nil. Ideally, I would want it to return the Constant that represents them.
class Sample def hello puts "Hello" end end #=> Sample
