Just FYI, the inability to have statements - even multiple statements
- in a lambda is what people are talking about when they talk about
the limitations of lambda. It's a common thing for someone with a
background that includes a proper lambda to trip over when they first
start programming in Python. It's not that uncommon for newcommers to
trip over it with "print".
