<p class="MsoNormal">this is the latest Squeak trunk version
replacing all duplicate unwind code with #unwindTo:safely:
(sent already as part of the other changeset with #terminate).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The modified version of #unwindTo: just
adds a Boolean distinguishing between the "old" unwind
semantics, i.e. only evaluating unwind blocks that haven't
started executing yet, and the "new" unwind semantics applied
in #terminate (safely: true enables the new semantics).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a bonus we can experiment with setting
safely: true even for "normal" returns, extending the unwind
semantics for non-local returns and exceptions. It's more or
less working but haven't been tested properly so this is my
project for later this year :)</p>
<p class="MsoNormal"><o:p> </o:p></p>

Hi Jaromir,<br>
<br>
A quick review of the code doesn't obviously seem equivalent (at
least in Cuis).<br>
<br>
Still, if you see value here, I can devote more time to try to
understand the differences.<br>
<br>
Thanks,<br>
