[Python-ideas] Re: IDEA: Allow override of all assignments of a built in type to be a different type

I've written my share of mathematical and physics software by now and arbitrary-precision rational numbers are hardly ever a good solution to problems you might be having. Paul Moore has mentioned how few keystrokes this syntax would actually save: add to this the fact that there are probably very few uses of arbitrary-precision rational numbers in real-world Python code and this will look a lot of added complexity for little benefit.
