Clearly one can continue to add libraries to Mathematica. Each time some computational functionality is added 'built in' it replaces a functionality (or potential functionality) that could be implemented in the Mathematica language, and may make someone somewhere happy. Many? I wonder how many people doing statistics are just waiting for extra features to be added to Mathematica (vs. using systems that already provide such features, and have done so for many years).. Possibly some other people will be inconvenienced by cost, size, complexity, etc. One hopes, not by much, if the design of features is properly orthogonal to other features. I do not object to the goal that a computer algebra system should generally be extensible and extended to cover as much of math as can be done "nicely". There are some designs that are especially uncomfortable -- for example imagine the result of merging pre-existing systems each of which has a different notion of "integer". My concern has been and continues to be based on the observation that Mathematica fails to fulfill reasonable expectations on simple things, for example arithmetic and comparison of floating point numbers. Therefore a package built on this foundation of sand may fail in mysterious (to typical users) ways. A package built by savvy programmers internal to WRI may fail less frequently than one built for similar purposes by an "outsider". RJF
