Thanks for reporting this, and thanks for nyacc!

Guix ships four distinct versions of nyacc:

  nyacc 0.86
  nyacc 0.99
  nyacc 1.00.2, and
  nyacc 1.04.0 (the default).

This still holds true on the current core-updates branch.

I'd expect the warning to be accurate for the 0.x series, but 
maybe they turned out to be more stable than expected :-)

Which version(s) of nyacc have ‘stable syntax and nomenclature’, 
and which (if any) did not?  

Kind regards,
