Interleaved lists and associative arrays

Hi, all,

I need write Tcl code to interactive with a Perl module. Perl may pass
me something like the following::

{
[
{ url => 'http://foo.org', title => 'The Foo Organsiation' }
{ url => 'http://bar.org', title => 'The Bar Organsiation' }
],
[
{ url => 'http://foo.org', title => 'The Foo Organsiation' }
{ url => 'http://bar.org', title => 'The Bar Organsiation' }
]
}

[] is equivalent to the Tcl list. However, I cannot find the Tcl
equivalence for {} (associative arrays). I know that Tcl has array
variables, which implement associative arrays. But it seems that array
variables cannot be embedded into a Tcl list. See the following
example:

% set webpage1(url) http://foo.org
http://foo.org
% set webpage1(title) http://foo.org
http://foo.org
% [list $webpage1]
can't read "webpage1": variable is array

Can any one shed some light on this problem? I am kind of stuck right
now.

Thanks a lot!

Best regards,
Jingzhao
