<p>We in the OTP team think this is a good idea but we can't say when we would have time to implement it.</p>
<p>It should be quite simple to implement mostly involving the module erl_lint.</p>
<p>A nice user contrib would make it possible to introduce quicker.</p>
<p>The possibility to turn on and off per function is not so important ,<br>
Can be added later if needed and would require some extra thought.</p>

that<br>
{ok,Foo} = bar(...),<br>
{ok,Foo} = ugh(...)<br>
is too easy to write (when you really meant, say, Foo0, Foo1).<br>
<br>
This is a well defined part of the language, and it would not be a good idea to<br>
ban it. But how about an optional style warning (and we really need<br>
-warn(on | off, [warning...])<br>
directives) whenever a bound variable appears in a pattern on the left of "="?<br>
