$s can be passed to another procedure and reused quite easily.

Oh wow, that's nice. I see that structures are created is a similar
manner to file channels, sockets and canvas items. So it feels familiar
and quite 'Tcl'ish. But how do you do nested [structure]?

Thanks. It doesn't have any explicit support for nested structures,
yet.

Have you tried compiling on other platforms? Where can I find your
extension?

I've compiled the extension in NetBSD, Linux, and Windows (with MinGW
IIRC).

The latest version of the structure code is here:
http://www.xmission.com/~georgeps/implementation/software/megapkg/megapkg-361.tar.bz2

The actual C code is in megapkg-361/csrc/structure/*.c

The tests for the extension are in megapkg-361/tclsrc/generic.img and
megapkg-361/tclsrc/tests/structure.tcl (the frontend).

To build structure.so in Windows with MinGW you'll need to do something
like this (after setting the build.conf paths):

tclsh8.4.exe build.tcl build.conf structure.so

Otherwise build.tcl would attempt to build every extension and binary in
megapkg, and unfortunately some of them target unix, and would thus
fail.

I seem to recall I did something with a dllwrap or dlltool manually when
I built it in Windows XP years ago. Patches to the build.tcl or
tickmakefile for Windows-specific builds would be appreciated. :)
