Ruby has regular commas:

[a, b, c]

Ruby has trailing commas:

[
 a,
 b,
 c,
]

But I think both of these are hard to read compared to the Oxford comma.
We should introduce the Oxford comma so that code is easier to read:

For example:

def foo a, b, and c
  [a, b, and c]
end

p foo(1, 2, and 3)

As an added bonus, this feature also makes specifying musical beats
quite natural, for example:

[1, and 2, and 3, and 4]

Just to make sure that everyone is pleased, you are allowed to mix the
Oxford comma with trailing commas like this:

[
  1,
  and 2,
  and 3,
  and 4,
]

This looks a lot like perl. Moving towards normal-text-like programming language may be a dangerous way.
Looks nice, but feels scary and unnecessary.

why not , or too?

What if there was a american_english: true magic comment that allowed this behavior? Then Ruby could support other English idioms and it would be extensible. Also British people could turn it off.
