    We no longer seem to need a matching "\right".

    E.g.
    \left(\dfrac12
    which isn't very useful.

    But also
    \left\{\begin{array}<br />
{l l}a_1x_1+a_2x_2+a_3=0 & \quad\text{(1)}\\<br />
b_1x_1+b_2x_2+b_3=0 & \quad\text{(2)}<br />
\end{array}
    ...which is!

    (Previously it was necessary to match the "\left\{" with a corresponding "\right." to avoid a syntax error. At least, I think it was ...)

    Hmm... Interesting.
