Add a way to check if function with specific arguments exists

Suggestion

Add a way to check if function with specific arguments exists as a expression

Why?

This could be useful if you have a function where want to check if your provided arguments can be used in the called function or not
A example on how this expression could be is:

if (function named "testing" with arguments player and true) exists:
    broadcast "yes this function exists"
else:
    broadcast "a function with these arguments dont exist"

Other

N/A

Agreement

• I have read the guidelines above and affirm I am following them with this suggestion.

What about more like can execute function with arguments?

This is kinda weird overall since a function cant exist with multiple signatures?

Multiple functions with the same name but different args can exists.
