Hi; In theory, Yes. But one could, if they want to, Unprotect Mathematica's Foo[] function first, and then they can define their own function to be called Foo[]. That is why it is common knowledge in the Mathematica community that no one would define a function name or symbol or variable that starts with UpperCase. http://reference.wolfram.com/mathematica/tutorial/DefiningVariables.html "There is a convention that built-in Mathematica objects always have names starting with uppercase (capital) letters. To avoid confusion, you should always choose names for your own variables that start with lowercase letters." Small price to pay for consistency and avoiding problems such this one here. Would you not agree? --Nasser --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
