Been thinking about this more, just trying to explore where this idea leads:
- Where tail merge would really shine is that a snippet could be embedded inside a div tag, for example, but still have a tail pushed to the end of the page body. - Script entries in the head and tail blocks could be quickly analysed and duplicate scripts removed. - Possibly some additional elements/attributes on scripts inside head and tail blocks could ultimately evolve into part of a richer dependency management framework.
