We/some-of-use/me thought it wood be a Good Thing so I added it to the reserved words, although we never got around to adding it. Not everyone was convinced. For info 'cond' is also a reserved word, another good idea we never got around to adding. :-) I have an extended 'cond' in LFE (can do pattern matching as a test) and it is useful.<br><br>Robert<br><br><hr id="zwchr"><blockquote style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><br><div><div>On 22 jul 2011, at 20:35, Tristan Sloughter wrote:</div><br class="Apple-interchange-newline"><blockquote>I think everyone has suggested let bindings at some point in time for Erlang :)<br><br></blockquote>'let' has been a 'reserved' word since at least 1998.

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div class="im">> I very much like the idea of a proper let (or a where) and I think it would make variable handling clearer. Variables are handled in a consistent way but it is not always easy to work out what should happen. Most people never ave problems with this as most people write pretty "simple" code (from the compiler point of view). Adding local functions, which I think would be a Good Thing, in the same way as variables are handled today would be very confusing so some form of 'let' construct would be necessary, at least for them. Then we might as well have for variables as well.<br>

</div>I like the idea of let bindings - I think someone has suggested this<br>
before. It might have been Richard, although apologies if I've got<br>
that wrong.<br>
