Hi, Rainer,

My point was that there is at least one (minor) case where properties 
are not functionally equivalent to the BABEL line: You cannot pass 
arguments for more than one variable buffer-wide, because you can't 
have multiple var properties at the same time, and at present, one var 
property only sets one variable.

The behavior of properties has not changed. What has changed is the 
removal of the BABEL header, whose colon (:var) syntax did allow you 
to set multiple variables buffer-wide should you wish to.

Yours,
Christian
