I disagree. A basic design choice in Sage -- since day 1 -- is not to make such a judgement. Sage is meant to be an easy to use system designed for mathematics, which happens to use Python as a language, instead of me creating a new language from scratch. Of course we have to take with what is introduced in the global namespace. But that you can start Sage and type sage: sin(pi) is not only *good*, but critical. Requiring all users to do a few imports before the above would be bad. -- William > > Best regards, > Simon > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. -- William Stein Professor of Mathematics University of Washington http://wstein.org -- You received this message because you are subscribed to the Google Groups "sage-support" group.
