Yes, and in Ruby2.0, this will be changed to "if you see an assignment
to a bare name, that name means a variable in the current scope", so
that

| def foo
|   n # method
| end
|
| def bar
|   n = 3
|   n # variable
| end
|
| def baz
|   n # will be variable
|   n = 3
|   n # variable
| end
|
|Note that it doesn't matter if the assignment is actually performed,
|just that the parser sees it:
|
| def hoge
|   n # will be variable
|   if false
|     n = 3
|   end
|   n # variable
| end

See?
