It has been a long time that I had a look at the bindings. In the 
original bindings, both possibilities with and without a symmetric 
adaptor were provided and what I suggest worked.

Having said that, I agree with Rutger that allowing to pass upper(a) as 
an argument would be much nicer (in most situations).
