I think that, without #<- being in all the major Smalltalks first, much less being common practice in the first place, it is not appropriate to discuss this for inclusion in the Smalltalk Standard at this time.<br><br>Andres.<br>

It all boils down to shorter code. You can write<br>
<br>
myArray := Array<br>
with: self this<br>
with self that<br>
with: aVariable<br>
with: #foo.<br>
<br>
<br>
But after you want more than 4 dynamic elements, you will need <br>
to do something else, such as create an OrderedCollection and<br>
start adding things to it, and then perhaps convert it to Array. <br>
You might decide to define a binary alias for #add:, like #<- <br>
to save a few keystrokes. <br>
<br>
The downside for adding extra syntax for this purpose is that<br>
it makes the standard thicker, and the language harder to learn.<br>
Harder to learn means easier to make mistakes, and errors.<br>

For me I don't know which one is better, it's a question of <br>
Obama vs. Hillary.<br>

Indeed, although for what it's worth there's no lingering debate<br>
there on this particular issue[1]. ;)<br>

Well, in Squeak 3.9 I get<br>

Welcome to the finale version of 3.9 of 7 of November 2006<br>

Having been living with Squeak for a while now I really, really like
the curly brace syntax. I also note that it doesn't conflict with e.g.
VisualWorks use of #{name} for binding references. So I have a strong
personal preference for it, but that's just personal.<br>
