# Assuming we're in an irb terminal.

# Keep in mind: 
# * The return value of assignment in Ruby is the thing you assigned.
# * Ruby includes syntactic sugar to invoke methods with no parentheses. So `puts` is equivalent to `puts()`

# So when we write `foo = puts`, we assign `foo` the return value of puts which is always nil.
# What we're actually saying (without the sugar) is:
# `foo = puts()`
