The Trunk: Compiler-mt.413.mcz

Marcel Taeumel uploaded a new version of Compiler to project The Trunk:
http://source.squeak.org/trunk/Compiler-mt.413.mcz

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

Name: Compiler-mt.413
Author: mt
Time: 21 November 2019, 4:23:15.551156 pm
UUID: db181638-e223-5648-8bea-f5084f9c44ad
Ancestors: Compiler-mt.412, Compiler-ct.407

Merges Compiler-ct.407. We can now programmatically handle syntax errors:

[Compiler evaluate: '3+?']
        on: SyntaxErrorNotification
        do: [:ex | ex resume: '3+4'].
