19.1. Function annotations

apply_in_context

[apply_in_context] function annotation. Function is modified, so that it is called in the debug agent context, specified in the annotation. If specified context is not insalled, panic is called.

For example::

[apply_in_context(opengl_cache)] def public cache_font(name:string implicit) : Font?

…

… let font = cache_font(“Arial”) // call invoked in the “opengl_cache” debug agent context
