http://code.google.com/p/pharo/issues/detail?id=6519 I really love seeing that happens. Thanks camillo! I like that because I spent time cleaning OCompletion to avoid duplication and being able to load it with ECompletion, Esteban did a pass and made my work working and now you give the final touch. I think that this is a good illustration of the power of improving infrastructure step by step and being able to build on the previous step. Stef
