Yes, but I have taken this change out as well as several others because I don't
use them anymore.  If someone wants them I can post them in a separate package.

When compiling a method, multiple references to the same literal are combined
together into a single literal and held in the compiled method.  Suppose you
have both 'foo' and #foo in your method.  If the compiler uses #= it would
incorrectly combine 'foo' and #foo.  Hence it uses #literalEqual: instead. 
Previously this test was coded in long form in the compiler and other places
like CompiledMethod>>= that tested for literals..

As far as I know they work in subclasses.  Some of been removed like
becomeClass: because they are no longer used.

Your right.  I removed this.

Your right again.  I removed this stack protocol from Collection.  And changed
my code to use normal OrderedCollection protocol.

I removed this one as well.

Goran answered this.  We want everything changeable within Squeak.
