Reduce-Reduce problem choosing a path

[Adam Smalin]

Here is an example of my input

thing { $var.member }

The problem is I allow

thing { .member $var }

So what is happening is I'd LIKE to always use $var.member but it can
reduce $var then .member which should not be allowed if $var is in front of
it (or $foo or $anything).

I'm not exactly sure where to put the precedence rule or how to. Both paths
take VarB but one reduces too early. I blindly put %dprec on VarB ('$'
VarName %dprec 1) and on Token (Token: Tokenb  %dprec 2 { ... }). But I
haven't used dprec and unsure how it works.I get the same ambiguity error
