Comment #9 on issue 1332 by dimac...(a)gmail.com: String literals are not cloned http://code.google.com/p/pharo/issues/detail?id=1332 My vote for immutable Strings. The actual behavior is, in my opinion, misleading.

So one would need to do a "JIT" that translates smalltalk to java... difficult, and a huge project in itself. The worst aspect: You need to be *the* expert on Java VM internals to do that. I am doing Pharo because this is exactly where I do not want to go. Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.
