You say that, but I find that a lot harder to read (and using `e` notation) than just the number - and readability / clarity is more important than cleverness, especially in Go.

10_000_000 can be read, 5 ＊ (1000＊＊4) and 1e7 has to be decoded. By me anyway, I'm just an average developer that never did well in maths - and you have to write code for the average developer, not for yourself and not for the top 10% smartest people.
