Well, there is question about correctness of proposed patch. I there were no alternative then the patch would be improvement on current situation. However, there is obviously correct alternative, that is always using a new symbol and you advocate reusing dummy from representation of derivative. Without proper justifiction for reuse I think we should use new symbol. Always using new symbol uncovers problem with testing machinery: when input form uses different symbol name it signals spurious error. So we will have to rethink our approach to testing. -- Waldek Hebisch -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
