A new version of Collections was added to project The Inbox: http://source.squeak.org/inbox/Collections-mt.812.mcz
==================== Summary ====================
Name: Collections-mt.812 Author: mt Time: 18 December 2018, 11:58:09.289023 am UUID: 64ff5a45-61b5-5642-aa46-9fbeac0215dd Ancestors: Collections-eem.811
Adds a small scripting/debugging interface to evaluate code on a heterogeneous collection. Ignore errors on the way.
1. Example: A bunch of morphs whose n-th submorph should be made yellow. Would raise errors for morphs with less than n submorphs.
ActiveWorld submorphs try: [:ea | ea submorphs fifth color: Color yellow].
2. Example: Fetch the selected classes of all code browsers through the submorph interface.
| results | results := OrderedCollection new. ActiveWorld submorphs try: [:ea | results add: ea model selectedClass]. results explore.
