LISP has two such functions 'cond' and 'if' which do the same thing as my
two examples.
In Common Lisp 'cond' is a macro and 'if' is a "special form". If you
wanted to write either as a function, you would have to write the arguments
to the invocation as closures to prevent them being evaluated before the
function is called. It also means that you can't pass 'cond' or 'if' as the
function argument to 'funcall' or 'apply'.
