|
|
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,

parentheses around X. */
