>Can code with underscore assignment still

Dont know ... at least it should since this works:

foo_bar
   | foo |
   foo _ 1

although i would go here with Sam about readability ;)

Attached is a changeset for latest trunk (3.11alpha#9676)
so you can try yourself.

It has a Preference (see PrefBrowser -> compiler -> allowSelectorsWithUnderscores) which is false by default.

If true an underscore is accepted and any code with underscores
is loadable without patching the image/Scanner class.

Does that satisfy anybody?

Please feel free to review and integrate if accepted.

Thanks to Ian Piumarta for the original idea/changeset...

Thx
T.

P.S: Typically the pref is included/initialized in 
     Parser class>>initialize but I dont call this method 
     in the postscript. The postscripts adds the preference
     directly. This will preserve existing compiler settings.
