Can someone provide or point me in the direction of an explanation of
what this means?

> [a] ++ b
[a|b]

Is this a quirk that has a useful side-effect that is a feature?  Or was
this an intentional feature from the beginning?  It reminds me of
something I saw in Lisp, the dot operator or something.  My memory fails
me.

Sincerely,
Eric Newhuis
