ccan includes many modules which use macro wrappers to make typesafe pseudo-templated versions of a basic algorithm or data structure.
This series implements several extensions to the tcon module to enable yet another approach to this. The advantage of this new method is that it's able to store a variety of "template" information into a type or variable declaration. That means that a module using this technique can implement typesafe wrappers which can obtain the type information they need from that initial declaration avoiding the need to respecify types or field members in multiple places. The last two patches in the series apply this approach to the lstack and lqueue modules, giving them a nicer typesafe interface. NOTE: The first patch in this series causes ccanlint to fail on the tcon module. AFAICT this is a ccanlint bug - it seems to be somehow getting out of sync and including entirely wrong comment lines into the example snippets. I haven't managed to figure out what about the changes is triggering the ccanlint bug though.
