It's because s]foo]bar] is really ugly, and because we didn't want to
make judgements about all the possible Unicode pairings as to whether
you could use them like �� but not like ��.

What to interpolate between elements will likely be a property
on the array. By default it should be a space. We may have a
universal method like @a.as('%s',' ') to modify that at the point
of interpolation. Could probably be written @a.join(' ') too.

A list in scalar context always returns a reference to the list.
That is, it assumes [...] around it. You have to use ...[-1] to get
the last element of a list.
