<div dir="ltr">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...

Better names for the preferences could be #disabled, #st80,
#ansiSmalltalk.<br>
<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>

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>
