I believe that is the case. Normally that will be fine, because
you can't modify them. Type-deduced lambda is a very special

No, wait a second. (a)=>a is in default argument list, so it

instantiate BTree with char.
Could you explain that

This is roughly what I originally had, but it creates a number of
