I would like to make a couple of small changes to the R grammar.
At present, operators like ~, ==, !=, <, <=, >, >= are declared
to be non-associative. This means that things like
a < b <= c
produce a "syntax error" message when typed.
I would like to change the grammar so that these operators are
left-associative. I want to make this change so that mathematical
annotation in the graphics will work a little better.
Interestingly, these operators are left-associative in S, so this
would be a move toward compatibility.
Does anyone have any strong thoughts on this?
