<div class="_rp_T4" id="Item.MessagePartBody">Spoken generally, Through should not only "step into a block", but rather "step until the activated context's home equals the currently displayed context home" (just as #stepToHome: describes). Or would you have
a different expectation?</div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;">Without exploring all pointers of thisContext (😱), I see no longer any feasible option in order to make sure that Through will impossibly reach a nested closure context. Maybe, we
could scan thisContext method for any closures, but I have the impression that such kind of edge case optimization would rather lead us to a new source of errors ...<br>
</span></div>
<div class="_rp_T4" id="Item.MessagePartBody">Actually, today I find it much more important to make sure that you can reliably use <cmd>dot to abort the stepping (and ideally, after that restart the context), without destroying your image. Investigating further
details about Active Process, #runUntilErrorOrReturnFrom: and, most urgently, recursive error detection in debugger seem appropriate ways to achieve this.</div>

<p>Hi all,</p>
<p><br>
</p>
<p>take the following snippet, debug-it and press "Through":</p>

<p><span><br>
</span></p>
<p><span>For me, it makes the debugger hang really long time, as apparently the whole code execution is simulated, searching for the current context (#stepToHome:). "Over", in contrast, is faster by far, calling #completeStep: instead.</span></p>
<p><span>Can we speed up "Through" in any way? As the button is explained as "Step into a block", we could call #completeStep: internally if the selected message does not contain a block argument, for example.</span></p>
