Name: Collections-ul.379
Ancestors: Collections-ar.378

- fix: ByteArray should understand #indexOf:startingAt: because StandardFileStream >> #upTo: uses it in binary mode. Also added a general implementation for SequenceableCollection.
- fix: Symbol class >> #allSymbolTablesDo:after: missed some elements, so Alt+q (Cmd+q on Mac) missed some selectors. WeakSet >> #do:after: was also responsible for some misses.
- enh: faster String >> #indexOfAscii:inString:startingAt:

=============================================

Name: Collections-ul.380
Ancestors: Collections-ul.379

- faster non-primitive String "primitives" by using #basicAt: instead of #at: + #asInteger/#asciiValue
- revert to #to:do: instead of a #whileTrue: in #indexOfAscii:inString:startingAt: , because that's also inlined even if the receiver type is unknown

This makes two significant changes to DateAndTime/TimeStamp either of which fixes a number of TimeStamp tests.

1.  Ensure that when the date is extracted from either DateAndTime or TimeStamp that the date is defined in terms of a DateAndTime.

2.  If a TimeStamp and a DateAndTime represent equivalent instances in time then allow #= to return true when comparing them.

These changes may be controversial.  As mentioned when I discussed this on the #squeak IRC channel there are conceptual differences between TimeStamps and DateAndTimes.  I don't disagree with this notion, however that is not how TimeStamp is implemented currently in Squeak.  I admit I'm taking the easier approach since I would have to give some serious thought and research into a 'proper' redesign of TimeStamp.

For now these changes make TimeStamp/DateAndTime at least work like they seem to be expected to based on the tests.
