123 specification is either an OP_OTHERS (others=>...), an

125 positional aggregates only). Aggregates currently

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