// ABIAliases are text symbols that should be aliased to all
// ABIs. These symbols may only be referenced and not defined
// by this object, since the need for an alias may appear in a
// different object than the definition. Hence, this
// information can't be carried in the symbol definition.

// in the concurrent phase. To ensure a deterministic order, we
// add them to a separate list, sort at the end, and append it
