+ OP_CHOICES operator. Next come N operands, each of which is an
+ expression, an OP_DISCRETE_RANGE, or an OP_NAME---the latter
+ for a simple name that must be a record component name and does
+ not correspond to a single existing symbol. After the N choice
+ indicators comes an expression giving the value.
+
+ In an aggregate such as (X => E1, ...), where X is a simple
+ name, X could syntactically be either a component_selector_name
+ or an expression used as a discrete_choice, depending on the
+ aggregate's type context. Since this is not known at parsing
+ time, we don't attempt to disambiguate X if it has multiple
+ definitions, but instead supply an OP_NAME. If X has a single
+ definition, we represent it with an OP_VAR_VALUE, even though
+ it may turn out to be within a record aggregate. Aggregate
+ evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a
+ record field name, and can evaluate OP_VAR_VALUE normally to
+ get its value as an expression. Unfortunately, we lose out in
+ cases where X has multiple meanings and is part of an array
+ aggregate. I hope these are not common enough to annoy users,
+ who can work around the problem in any case by putting
+ parentheses around X. */
