I am needing a small utility (tk?) that will allow the context to be set manually by the interactive user dynamically (for a particular problem). Its like, one context doesn't fit all. Some of the pdeclib funcs will need to take into account the various signals also. The context manger is fabulous, but not for the average user; all the try block stuff is encapsulated (which makes the coding clean) but it is not obvious in any way what is happening with __init__() , __enter__() and __exit__() (although I did find a couple of good articles on the subject. The 'with localcontext(cts=None) as ctx' is genius, but not for the average user who just wants to get work done with python. So, the bottom line is we have this fabulous speedy decimal module that is nothing short of wonderful for experts, and completely out of the grasp of average users relatively new to python or with limited experience with decimal floating point arithmetic. "They would like to sing soft and sweet, like the cucumber, but they can't!" So, we need a complete wrapper around the decimal module (or better yet we need to make decimal floating point default) so that average users may take advantage of precise floating point math without having to be experts on decimal floating point arithmetic constraints in the new high speed module. :-} marcus -- https://mail.python.org/mailman/listinfo/python-list
