Hilaire, please check that the use of Preference NG is reasonable.<br>
<br>
Folks, please check that the names and default I used make sense.<br>

<div>The only concern I have with this is that I do not think that
using preferences for the syntax of the language is a good
idea... it will make incompatible cuis code depending on how the
preference is set... I do not have a better solution (only the
one I suggested earlier :-) ), so I do not have a strong
opinion against it, I do not like the idea but I can live with
it and see how it goes.

Let's hope that whoever modifies that preference knows what they are
doing.<br>
For example for loading code for Pharo. In that case, the default
behavior will break stuff.<br>
Shortly, I'll try all packages in the Cuis-Smalltalk github
organization with the preference at #disabled, to find and fix
existing code that would break in such case.<br>
<br>
Besides, I suggest having it at #disabled when writing code, to
avoid unneeded suffering in the future.<br>
<br>
Thanks,<br>

Default could be #st80 (meaning `1@-2` answers the same
Point as `1 @ (-2)`.<br>
<br>
If nobody disagrees strongly, I guess I'll push it like
that, using Hilaire's new PreferenceNG.<br>
<br>
Thanks!<br>

Given the path followed by Squeak and Pharo, and what ANSI
Smalltalk says, and the preferences several of you just
said, the attach is my proposal.<br>
<br>
It adds a new preference #atMinusDigitMeaning. Possible
values are: #disabled, #negativeNumberParameter and
#atMinusSelector. It doesn't only control '@-', but any
binary selector ending in $-, with size > 1.<br>
<br>
The question is what to use as a default value.<br>
ST-80 and Squeak go with #negativeNumberParameter. <br>
ANSI Smalltalk and Pharo do #atMinusSelector. <br>
#disabled is also a reasonable alternative, helping
programmers understand a smell in their code.<br>
<br>
Thanks,<br>
