width of null delimiter

Hi,

I'm using the delarray package for grouping statements with a curly
brace on their right. But I also want the left to be aligned properly;
and I suspect the "null" delimiter "." is taking some width.

How do I get (1), (2) and (3) to be properly aligned here?

$$\begin{array}.{@{}>{$}l<{$}}\}
$\begin{array}.{@{}>{$}l<{$}}\}
(1) something with $math$ \\
(2) something else
\end{array}$
some more text with $math$ \\
(3) blah
\end{array}
pure math here
$$


Thanks,
Maarten.
