120 specification is either an OP_OTHERS (others=>...), an
121 OP_CHOICES (for named associations), or other expression (for
122 positional aggregates only). Aggregates currently

129 /* An aggregate component association. A single immediate operand, N,
130 gives the number of choices that follow. This is followed by a second
131 OP_CHOICES operator. Next come N operands, each of which is an
132 expression, an OP_DISCRETE_RANGE, or an OP_NAME---the latter
133 for a simple name that must be a record component name and does
134 not correspond to a single existing symbol. After the N choice
135 indicators comes an expression giving the value.
137 In an aggregate such as (X => E1, ...), where X is a simple
138 name, X could syntactically be either a component_selector_name
139 or an expression used as a discrete_choice, depending on the
140 aggregate's type context. Since this is not known at parsing
141 time, we don't attempt to disambiguate X if it has multiple
142 definitions, but instead supply an OP_NAME. If X has a single
143 definition, we represent it with an OP_VAR_VALUE, even though
144 it may turn out to be within a record aggregate. Aggregate
145 evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a
146 record field name, and can evaluate OP_VAR_VALUE normally to
147 get its value as an expression. Unfortunately, we lose out in
148 cases where X has multiple meanings and is part of an array
149 aggregate. I hope these are not common enough to annoy users,
150 who can work around the problem in any case by putting
151 parentheses around X. */
