<div dir="ltr">Exactly. Short-circuiting is emulating laziness in this one case where it turns out to be generally useful. And while (_|_ && _|_) may be evaluatable from a logical standpoint, computer languages tend to not do well with it: regardless of how it evaluates, (&&) is going to try to force at least one of the bottoms.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 12, 2019 at 9:19 PM Theodore Lief Gannon <<a href="mailto:tanuki@gmail.com">tanuki@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div>I think Brandon's point is that short-circuiting is in fact an example of lazy evaluation, regardless of the language being otherwise strict.<br><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 12, 2019, 4:52 PM Stefan Monnier <<a href="mailto:monnier@iro.umontreal.ca" rel="noreferrer" target="_blank">monnier@iro.umontreal.ca</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">> Er?

Exactly: with lazyness, either associativity gives the same result,<br>
and without lazyness either associativity also gives the same result.<br>
The two seem orthogonal to me.<br>
