In Ruby, everything starting with a capital letter is a constant.
Constants are visible globally anywhere in a program, hence you can
access it in your method.

The =E2=80=9Cdef=E2=80=9D keyword creates a new scope where you can=E2=80=
=99t access veriables
from the outside, which is why you can=E2=80=99t see them inside the method.
