Hmm, the current rule is that all arguments are packed in an array,
and you can specify a hash without braces at the end of the argument
list, so that

 test(1, 2, 42)       # [1,2,42]
 test(1, 2, 3, 4)     # [1,2,3,4]
 test(1, 2, 3, 4=>5)  # [1,2,3,{4=>5}]

are passed by the caller.  This does not require any callee side
argument tweaking.  I think I can understand the rule you want, but
it's rather complex, especially in combination with optional arguments
and rest argument.
