You obviously haven't used more than one templating system. HTML::Template works along the pipeline you describe. Petal, HTML::Mason and Template Toolkit allow various forms of callbacks, all with different notions and notations.

The notations could possibly be abstracted away for a backend, but you need something like HTML::Template::Expr, if you want callbacks in HTML::Template - and samtregar has stated it on more than one occassion that such stuff is outside the scope of HTML::Template.

Letting web developers use different template languages within one site is a sure recipe for disaster - it's akin to liberally allowing use of Inline::C and Inline::Assembler within a project - you instantly lose the capability to let one person work on another page.
