<div dir="ltr">Hi,
<div> I just added to Cuis-Smalltalk-Dev/Packages/System a
package to set an object as immutable. </div>
<div> The package name is <a moz-do-not-send="true"
href="http://Immutability.pck.st">Immutability.pck.st</a>
and it has tests in <a moz-do-not-send="true"
href="http://ImmutabilityTest.pck.st">ImmutabilityTest.pck.st</a></div>
<div><br>
</div>
<div> To make an object immutable just send the
message #beImmutable to it. To make it mutable #beMutable.</div>
<div> If you try to modify an immutable object the
ModificationForbidden exception will be signal which is
resumable.</div>
<div><br>
</div>
<div> Please, look at the tests for more examples.</div>

<div>Cheers!</div>

Very nice, Thanks!<br>
<br>
Next steps include how to make method literals be immutable.<br>
<br>
Something else that would be great is to gradually make Strings
immutable. That would allow us to replace String with Rope if
desired.<br>
<br>
Cheers,<br>
