The intention of the proposal was to allow any portion of something that
can be rung to be given a name that describes what is rung rather than
having to construe it as something else. Dixons is a totally different
type of construct - more a composition than a method - since the changes
to (E) A.2in 2011, Dixons can be described as a composition of Plain Bob.

Non-method blocks do not have leads. One possibility discussed was not
to provide for calls at all, but this might lead to a situation where a
palindromic block in a palindromic composition with different places
made at either end would have to be given different names in each half
of a part.
Regardless of the detail the main effect of the motion is to separate
the definition of a compliant peal composition from that of a method
(which I have long advocated), without changing what could be construed
as either. Effectively a compliant peal composition must satisfy
(D)A.1-3 and B.1-7: the rest just determines how it is described.
I am genuinely surprised at the amount of opposition to the motion,
which seems mainly to hinge on the previously unsatisfied demand to be
able to ring compositions of false "methods". The alternative would have
been to propose something that might have been defeated as a result of
pleas from those who prefer to think of a method as something that
should be worth ringing in its own right.
