Now you could explore this yourself.  First, as a reference inspect
"Collection withAllSubclasses" on its own.
Then try debugging into the expression (from the context menu in the

In particular in OrderedCollection>>collect:  step-INTO   "aBlock
value: ....."

For an even lower level (probably too low), try debugging into...
OpalCompiler compile: 'Collection withAllSubclasses collect:

or more simply debug...
OpalCompiler compile: '#numberOfLinesOfCode inspect'.

Other things you could explore
* Look at the class comment for class Symbol
* Look at the tests of class SymbolTest
* In the Browser with class Symbol selected, right-click and choose
Analyze>Class refs.
