Incorrect use of "either" in section 2.1

[mikong]

The second paragraph of section 2.1 reads:

(original)

Integers can, alternatively, be expressed using hexadecimal, octal or binary notation using either of these prefixes: 0x, 0o or 0b.

The use of "either" seems inappropriate given the 3 options. "any" is typically used for 3 options but I wouldn't replace "either" with "any" in this case since you can't just use any of the prefixes if you need a specific notation. It seems better to just remove "either of" and then add "respectively":

(revision 1)

Integers can, alternatively, be expressed using hexadecimal, octal or binary notation using these prefixes respectively: 0x, 0o or 0b.

I would like to move "alternatively" to the start as well, although this is just a matter of preference:

(revision 2)

Alternatively, integers can be expressed using hexadecimal, octal or binary notation using these prefixes respectively: 0x, 0o or 0b.

I can make a pull request if people agree with these changes.

I'm a random Rust n00b going through rust-by-example, and also noticed this incorrect use of "either". Both of your suggestions seem like improvements to me.
