I have heard that Fortran can outperform C++ in numeric computation around the percentage you mentioned but first time I heard that its generally faster.

In any case my point was that if namespaces can be done in a badly design language , should be possible in Pharo and easier. Not ease, just easier. Of course that's just a wild assumption but I hope this thread do not only disaprove my assumption but said a light in the real challanges of namespace implementation
