That's how Smalltalk works. It has no "if" statement. There's an "IfElse"
method that takes two blocks. True evaluates its first argument, False its
second, in a polymorphic way. So

bool if: [yes yes] else: [no no]

doesn't contain any branching code. Just a polymorphic dispatch. Very
strange to wrap your head around. :-)

(Of course, in reality, it branches for efficiency, recognised by the
compiler, but in theory...)
