Just looked into this.  They are not methods, they are callables:  
BTrees.Length.Length objects return their values when called.  The  
indexes comply with the zope.index interfaces, and in fact are tested  
to do so.  That said, you and Thierry are quite right that they do  
not display correctly in the advanced catalog view.  We don't use it,  
so I didn't care.

I just added the necessary security declarations to make this work.   
Unfortunately I had to reach out of the package to make a security  
declaration on BTrees.Length.Length.__call__; this is a bit ugly, and  
ideally we'd address this sometime.

svn up to get the necessary changes.
