This was shut down without much discussion at
https://github.com/golang/go/issues/42.
I agree that it's a nice feature.
By the way, though, one nice aspect of Go is that because of how
untyped constants work you can write integers using scientific
notation:
for i := 0; i < 10e6; i++ {
// ...
}
This is exactly the same as if you had written 10000000.
(I don't think you'd want to do this in C or Java because, although it
would "work", 10e6 is a floating point number and so i would be
converted to a double for comparison. I am not an expert in those
languages, though, so someone can correct if I'm wrong here.)
