Synopsis

This LEL class is derived from LELArray. Its purpose is to provide only const access to the array value, so the array can be a reference to another array. It is meant for optimization, so references can safely be used when evaluating a subexpression.

Motivation

It makes it possible to use the function evalRef in a safe way. It would be unsafe to use a LELArray object, because that gives non-const access to the value.
