Hi Lukas,

You wont get rid of them just by removing the option. :(

There is a lot of "legacy" code out there that is not converted
and will then not be loadable in Pharo >= 1.2 or greater.

Keeping the option would allow to load this code and convert
it to standard assignment in the future. Otherwise
one has to use Squeak or Pharo < 1.2 to convert before using
it in recent images.

On the other side we havent cared on backward compatibily too
much anyway (yet) ...

Bye
T.

Re: RBScanner>>#initializeClassificationTable

I agree, removing the option in Pharo 1.2 is maybe a bit early. The
idea is to gradually increase the pain of underscore assignments, to
finally get rid of them.

That's fine. But the scanner still needs to support them always because otherwise you'll get a syntax error parsing old source files containing underscores. That's the intent of my Scanner>>#initScannerForTokenization method which is used by the ChangeScanner so that old files can still be examined.

Right?

In reply to this post by Torsten Bergmann

I would prefer to make sure that we ensure that people can load file with underscores. And one day we discard that.
