Hello.
I noticed today that it is very easy to get the first few characters of
a String:
string[0..whatever]
however, it is harder to get the last few characters of a String
string[-8..-1] || string
Feature request/proposal:
String#last(n)
like
string.last(8)
Feedback welcome.

If you think you really need it, you can just monkeypatch it in. Then
if you are finding it very useful, you can request it be added to the
class as distributed.

There's always the two argument form of slice:
"my string"[-3, 3]
# => "ing"
Not quite as nice as yours, however.

You should add this request to the bug tracker to ruby.
I don't think matz and many others regularly read every mail here. 
I do agree with you - I think .last(5) would be nice and more readable
than "foobar"[-5,5] # => "oobar"
"foobar"[-5,5] # => "oobar"
"foobar".last 5 # => "oobar"
But I also must say, I am now so used to use [] that I don't use
anything else. For the record, I also don't use .slice
I just love [] too much.

I think these are good methods too. They are defined in Ruby Facets, but in
a bit different way then one would expect.
I'd like to go whole hog here and propose Ruby adopt the Indexable module.
however, it is harder to get the last few characters of a String
string[-8..-1] || string
You could try something like this.
str = "123456789"
p str[/.{1,8}\z/]
p str[/\A.{1,8}/]
Harry
string[-8..-1] || string
...
There's always the two argument form of slice:
"my string"[-3, 3]
# => "ing"
And it still has this "feature":
>> "123"[-5,5]
=> nil
