Container for Template Rendering

[jbee]

A Injector container could be used to render templates (do string substitution with actual values).
The benefit would (must) be that this would validate when bound that template rendering does not lack substitutes for placeholders. Also rendering requires flexible render-functions that translate a value to a string representation.

The placeholders become a required named String (or a special type to distinct).
Than bridges are bound to make named values available as named values of that output type,
applying some conversion, that is also configurable via binds.
Provides should be used to make sure that template rendering in principle does not lack data.
