org.ek9lang.compiler.phase5.MakesIdentifierSubsequenceAccessSafe

All Implemented Interfaces:

Predicate<EK9Parser.IdentifierContext>

final class MakesIdentifierSubsequenceAccessSafe
extends Object
implements Predicate<EK9Parser.IdentifierContext>

A bit of a catch 22, need to issue errors and the like when traversing an identifier in some circumstances. But not if the identifierReference is actually being used in a 'is-set' test. But it maybe that this is an assignment which then makes subsequence access SAFE. So I don't like doing this sort of thing because it makes the grammar fragile. But here I need to traverse back up the grammar structure to see if this identifier is being used as part of a '?' expression or a safe assignment.
