elif could be a function that takes a boolean. Ruby can’t know this
until it interprets the line, because you might have used eval() or
something to create that function before getting here.
In exchange for a lot more flexibility, Ruby does fewer sanity checks
at parse time.
To keep Ruby on track, and catch errors like this, all Ruby developers
should write unit tests for everything.
