That's just poor programming.

Well, we have expressions. Look on the bright side you don't have to
wrap with unnecessary begin ... end blocks and have needless
connecting words like 'else' spread everywhere like you do in less
well-designed languages. If you really need a more classic style
syntax look at Lisp Flavoured Erlang or Effene (albeit different
classic).
