In order to give a more constructive feedback, why not simply indexing
arguments by position and use the `_N` syntax?
The second example would be:
_0 : _1 : _1 : _2 : _2 : _2 : _0 : 
One could just use `_` if there is only one arg:
_ + _ (which mean what Kim thought it would mean)
_0 + _1 (for the case you wanted to support)
