> What are the major issues with const/immutable and ref?

Const and immutable seem to be difficult to work with, Maxime 
wrote a piece about how difficult to use they were in practice. 
Ref is difficult to combine properly with generic templates, Manu 
covers that in another thread here.

Manu's post about the combinatorial complexity of ref for 
templates (which you've responded to earlier in the chain):
