Apologies for being late today... 'twas distracted by my English

## One-Liners Mashup (#177)

This week is going to be very informal, and without any particular
task or submission. It's hunting season, and we're hunting one-liners.

Basically, we'll start with the simple problem I've presented below.
Your solution must fit in one line. (Golfing is okay, but not
necessary. One line *generally* means about 80 chars wide, but we're
flexible here.) If you are writing a method, the `def foo(args)` and
`end` (and `class Whatever` and `end` for adding methods to a class)
doesn't count... the body of the method will.

Of course, your solutions should be generally useful, and not hard-
coded to solve any particular example used to illustrate what the
solution should do.

Post your solution AND a followup problem for others to solve. Repeat
ad nauseum (or until about Wed/Thu).

Ready? Here goes. First problem...
You should know this pattern well:

    > [:one, "two", 4] * 3
    => [:one, "two", 4, :one, "two", 4, :one, "two", 4]

Write a single line method on Array that does this instead:

    > [:one, "two", 4].repeat(3)
    => [:one, :one, :one, "two", "two", "two", 4, 4, 4]
