Thanks for the heads up - I'll be sure o stay out of their code and
only work with Gnu0-Smalltalk to the extent that we can polyfilla over
them.

I'll contact Paolo, although his last statement pointed to:
http://smalltalk.gnu.org/faq/32

"Does copyright restrict the use of GNU Smalltalk?
By Paolo Bonzini - Posted on June 20th, 2007

It does, but in general you don't need to worry much about the
licensing of your Smalltalk programs.

The class library is licensed under the GNU LGPL. Thus, it permits
using the library together with non-free programs.

The virtual machine and the bindings to external libraries are
licensed under the GNU GPL, with a special exception that allows
Smalltalk programs to be linked with the functions exported by the
virtual machine and said bindings."

and "whatever happens Smalltalk programs are clear and only covered by the GPL."
(http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-January/123790.html)

The LGPL states "You may convey a Combined Work [i.e. a work
containing both LGPL'd source code and non-LGPL's source code] under
***terms of your choice*** that, taken together, effectively do not
restrict modification of the portions of the [LGPL'd code] contained
in the Combined Work".

If we use LGPL'd Smalltalk from Gnu-Smalltalk, we may not close the
LGPL'd portion of the code.

Was anyone planning on closing the Unicode parts of Cuis/Pharo/Squeak?

It *is* an issue with Dolphin's .exe facility, which is one of my own
personal use-cases.  But for Pharo/Squeak/Cuis it seems to be a
non-issue.  If anyone has concrete evidence to the contrary, please
raise it now.


(IANAL but I can read contracts and do risk management of legal
issues).  If anyone continues to have long-term concerns, let me know.
I can get some qualified legal opinions.  Tbh, very little of my work
is done in the USA's legal jurisdiction.  My own risk is low.
