As the issue is about potential reuse of GNU Smalltalk code snippets / classes regarding Unicode the most straightforward thing is to ask Paolo Bonzini (http://smalltalk.gnu.org/blog/bonzinip) if he permits the reuse under an MIT license. So far no code has been identified which would be needed under an MIT license. HTH Hannes On 12/7/15, Martin Bähr <mbaehr@email.archlab.tuwien.ac.at> wrote:

randal schwartz suggests a cleanroom approach, though i personally think that is overkill. if a cleanroom approach were really necessary than i would never be allowed to switch jobs because once i have been working on one companys private code i would be tainted for life, as i could accidentally reproduce the same code in my next job.

however, either you get the GNU-smalltalk authors to relicense their unicode classes under the MIT license, or they will need to be rewritten from scratch.

i would suggest asking them in the name of having a common code-base for all smalltalks.

http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-January/123817.h... is worth reading in that context:

So it's mainly an issue of being willing to cooperate. I think all GNU Smalltalk people (almost all?) are and it's also true at least for some Squeak people. If somebody took a package (several thousands lines of code, etc.) wholesale, ported it to Squeak, and licensed it under MIT on SqueakMap that would be copyright violation. But everything can be done "cum grano salis". Nobody is going to sue you if you copy an interface from GNU Smalltalk, reimplement in Squeak (for fun!), but you did look at the method comments in GNU Smalltalk -- and OMG maybe you got a glimpse of the source code just below! Copyright does not protect having similar implementations.

I think we're all for interoperability and for exchange of opinions within the communities.

so there you have the open invitation to go and ask...
