If A == B, so A's types is the same of B's type. How can it be
withstanding `foo => bar` == `foo => bar` == `(foo) { return
bar; }` and `foo => bar` is an expression and the other is a
function?!! no sense.
`foo => bar` and `(foo) { return bar; }` are both function
literals, and they're both expressions. The concepts are not
mutually exclusive.
