Reading the documentation I understand that Lightning is quite lower level 
(compared to MIR for instance) since the API 
directly deals with registers yes? So the API user has to so his own « register 
allocation/handling machinery »? There is no notion on an infinite set of 
variables that can be defined and used ?
