Is there a way to define new delimiters in LaTeX math mode,
other than the existing () {} <> | etc.?

What I am after is a the semantics meaning delimiters, which
look something like this:

=======                   =======
|  |                         |  |
|  |                         |  |
|  |                         |  |
|  |                         |  |
|  |      Expression         |  |
|  |                         |  |
|  |                         |  |
|  |                         |  |
|  |                         |  |
|  |                         |  |
=======                   =======

Of course, I want it to change size in accordance with the size
of the expression, as \{ Expression \} would.

Thanks
