+1 on that point, which i failed to mention. :P

separating the logic from the template adheres more the common best
practice of using the MVC pattern. the template represents the "view,"
or the HTML template -- usually you want to keep this out of the hands
of developers and give it to your designers (UX/UE/UI) folks. on the
flip side, you want the controller (logic) to be the responsibility of
the programmers. this segregation of duties enables for more agile
development and creation of more accurate (and less confusing)
unit-testing and faster and cleaner development overall.

outside of the loops and conditionals mentioned, any real chunk of
code embedded in a template i'd consider a special case or deployment
issue (fewer approvals needed to push non-code, no need for server
restart on static file pushes, etc.).
