Here is a little Ruby trivium for you.
Type this into IRB:
def foo def bar 1 end end foo.bar => 1
Is this some magical lightweight object creation syntax so you can do cool method chaining? Let’s try another example:
def foo def foo 1 end end foo => nil foo.foo => 1
So far so good. But now, type:
foo => 1
WTF? Is this a defect in Ruby?? Post your responses in the comments.
(Warning: this is a trick question)
