> This can be solved by simply choosing a different name:
>      iif(cond, expr, expr)
>      when(cond, expr, expr)
>      cond(cond, expr, expr)
>      check(cond, expr, expr)
>      ...

-1 too.

(1) In order to do short-circuiting evaluation, the name would have to
    be recognized by the parser, which means it would have to be a new
    keyword.  None of these keywords sound attractive.

(2) It looks too much like a function call for my comfort.

I still like

    (if cond then expr else expr)

better than any of these.
