This won't work when leading zeros are involved, e.g. consider `123_006_789`: `t(123, 006, 789)` gives a SyntaxError. Also it's weird that when we want to write an int literal that we end up with two function calls and individual numbers as arguments (+ you'd need to have that function handy in the first place). It would be clearer to use a kw-only argument `base=1000` but even then it doesn't really convey they idea of a literal. > > If you're dealing with really big integers (say 1000 digits or more) > > then you might be want to use https://pypi.org/project/gmpy2/, in > > which case you'll appreciate the extra flexibility provided by > > t10.
