- 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. */
