)

const [inline]

Finds a function, searching from a specific environment

Parameters:

name	name of the function
env	environment where to find it calls the function with the specified arguments
...Args	variable length argument list. The type of each argument must be wrappable, meaning there need to be a wrap function that takes this type as its parameter
