My understanding based on the core team's comments was that `where` was introduced in the hopes of supporting some pattern matching that was abandoned.

It'd be amazing.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">

By contrast, the `where` clause violates that expectation and I do not see "overwhelmingly large advantages" for doing so.<br>

> I think you might be slightly misunderstanding Chris's point here. In the thread you quoted, somebody suggested fundamentally changing the very structure of the syntax—the way blocks are marked out—to something completely different from C. Chris said that such a huge deviation from the C family would need "overwhelmingly large advantages" before they would accept it.<br>

> This is not the same situation. It is true that there's no similar feature in C—mainly because C's loose typing allows you to use && instead—but the `where` clause is a mere augmentation of C practice, not a complete break from it. It does not need to pass nearly so stringent a test.<br>
