That should NOT compile. You're initialising a _reference_ to non-const
'float' using a _literal_ of type 'int' (the zero). If your compiler
does not complain, throw it away and get a better compiler.

Once you do, rethink your decision to store references in your nodes.
References are very delicate things, they cannot be "re-seated" to refer
to a different object. Once initialised, they refer to the same object
as long as they live; assigning to a reference changes the object to
which the reference refers.
