/* An aggregate component association. A single immediate operand, N, |

gives the number of choices that follow. This is followed by a second |

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. */ |
