Marcel Taeumel uploaded a new version of Morphic to project The Trunk:
http://source.squeak.org/trunk/Morphic-mt.1514.mcz

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

Name: Morphic-mt.1514
Author: mt
Time: 5 September 2019, 2:36:47.777837 pm
UUID: 49f63b40-72ce-c447-9fb0-9400ea43fab2
Ancestors: Morphic-mt.1513, Morphic-ct.1501

Merges Morphic-ct.1500. and 1501.

Can't we just filter for #isAlphaNumeric? Do we need parentheses etc.? Would be more readable than  ">= 32". I also do not think that #caseOf: helps much in terms of readability. ;-)
