[Cuis-dev] Immutability package

[Hernan Wilkinson]

Hi,
 I just added to Cuis-Smalltalk-Dev/Packages/System a package to set an
object as immutable.
 The package name is Immutability.pck.st and it has tests in
ImmutabilityTest.pck.st

 To make an object immutable just send the message #beImmutable to it. To
make it mutable #beMutable.
 If you try to modify an immutable object the ModificationForbidden
exception will be signal which is resumable.

 Please, look at the tests for more examples.

Cheers!
Hernan.
