When calling error or warning in a @Check method, and passing the wrong literal, the error message could be more helpful.

In my case - the call:

error(
"A selector expression must have at least one right side entry", o,
PPPackage.Literals.BINARY_EXPRESSION__LEFT_EXPRESSION, INSIGNIFICANT_INDEX,
IPPDiagnostics.ISSUE__NULL_EXPRESSION);

Produced the error: EClass 'SelectorExpression' does not expose a feature 'leftExpr'.

I should have used PARAMETERIZED_EXPRESSION__LEFT_EXPRESSION but was fooled by seeing only the name 'leftExpr' (which it indeed does expose).

Suggest that either the full identifier "BINARY_EXPRESSION__LEFT_EXPRESSION" is displayed, or that it also checks if the feature reference is made with a compatible EClass.
