[Feature]: Call js functions directly through macro:// uris

[Tdue21]

Feature Request

Currently when I want to execute a javascript function in a GraalVM context from e.g. a macroLink, I have to wrap this function in a MTScript macro, and call that. It isn't a huge deal, but it is annoying that I have to add a wrapper macro for every js function I want to call from a macroLink.

I suppose the same goes for an UDF as well ;)

The Solution you'd like

I would like to be able to call a function directly through the macroLink syntax (for lack of a better word), in the same way I call a macro.

I would like to be able to do something like this:

macro://js.functionName@lib:namespace/impersonated/?...

Alternatives that you've considered.

No response

Additional Context

I am currently working on an add-on library where as much code as possible is javascript. So far I have managed to limit my MTScript to three macros, onFirstInit, onInit and a generic evaluateMacro that can be called via fetch.

But I miss the possibility of calling a function direcly, like I can with macros.
