A BlockClosure is a lexical closure.
The JavaScript representation is a function.
A BlockClosure is evaluated with the `#value*` methods in the 'evaluating' protocol.!

!CompiledMethod commentStamp!
CompiledMethod hold the source and compiled code of a class method.
You can get a CompiledMethod using `Behavior>>methodAt:`
String methodAt: 'lines'
and read the source code
(String methodAt: 'lines') source
See referenced classes:
(String methodAt: 'lines') referencedClasses
or messages sent from this method:
(String methodAt: 'lines') messageSends!

Object subclass: #Message
instanceVariableNames: 'selector arguments'
package: 'Kernel-Methods'!
!Message commentStamp!
Generally, the system does not use instances of Message for efficiency reasons.
However, when a message is not understood by its receiver, the interpreter will make up an instance of it in order to capture the information involved in an actual message transmission.
This instance is sent it as an argument with the message `doesNotUnderstand:` to the receiver.
See boot.js, `messageNotUnderstood` and its counterpart `Object>>doesNotUnderstand:`!

!MethodContext commentStamp!
MethodContext holds all the dynamic state associated with the execution of either a method activation resulting from a message send. That is used to build the call stack while debugging.
MethodContext instances are JavaScript `SmalltalkMethodContext` objects defined in boot.js
Current limitation: MethodContext instances are not created on Block evaluation. That means it's actually impossible to debug inside a Block.!
