136 not correspond to a single existing symbol. After the N choice

138
139 In an aggregate such as (X => E1, ...), where X is a simple
140 name, X could syntactically be either a component_selector_name
141 or an expression used as a discrete_choice, depending on the
142 aggregate's type context. Since this is not known at parsing
143 time, we don't attempt to disambiguate X if it has multiple
144 definitions, but instead supply an OP_NAME. If X has a single
145 definition, we represent it with an OP_VAR_VALUE, even though
146 it may turn out to be within a record aggregate. Aggregate
147 evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a
148 record field name, and can evaluate OP_VAR_VALUE normally to
149 get its value as an expression. Unfortunately, we lose out in
150 cases where X has multiple meanings and is part of an array
151 aggregate. I hope these are not common enough to annoy users,
152 who can work around the problem in any case by putting
