Eliot Miranda uploaded a new version of Compiler to project The Trunk:
http://source.squeak.org/trunk/Compiler-eem.379.mcz

==================== Summary ====================

Name: Compiler-eem.379
Author: eem
Time: 20 March 2018, 3:27:27.12646 pm
UUID: b3856f24-9d98-478a-936f-c6d24d667be4
Ancestors: Compiler-eem.378

Add initialization of the Undeclared variable addedExtraLiterals which is soon to be a replacement for Encoder's addedSelectorAndMethodClassLiterals, a name which is now misleading given the new full block support.  By adding the initialization of the Undeclared variable the compiler is not broken as the instance variable is renamed and Encoder's methods are recompiled.
