Hi all,

for specifying the syntax of operator expressions
with multiple levels of precedences,
there are essentially two approaches:
(i) by precedence and associativity declarations, and
(ii) by a hierarchy of non-terminals.
Both approaches have been known and in use for decades.

My question is:
Are there trends in the public opinion
in favor of one of them over the other?
Or are they equally respected approaches?

Best regards,
Andreas
