and do the same lookup as foo() does, and using a (wrong)
functional-programming-inspired syntax

    foo 5 ()

Such a syntax will have the side benefit of allowing calling print in a
similar way to Python2, which people seem to love.

    print "hello" ()

This strawman proposal has many downsides I guess. My point being, this can
be made to work, but it's probably not worth it.
