named diversions

[Matěj Týč]

Hello again,
In my m4 project where I use autom4te and m4sugar (for those who are 
curious - https://github.com/matejak/d8 ),
in order to be able to output anything, one has to call
m4_divert_push(1) (or something similar) at certain point. However, 
every time I do that, I get the
warning: prefer named diversions
warning. I know that I can use m4_divert_push(KILL) in place of 
m4_divert_push(0), but a trivial diversion e.g. for stdout is not 
available (or documented). There is also a lack of documentation on how 
to register a named diversion, using a macro instead of a number isn't 
the right way how to make a named diversion.
Do you have any solution to this in mind? Telling autom4te to suppress 
warnings doesn't feel right.
