f++ example

Example of scope being used with f++: 

function(example.fn)
{
	:={scope+="teji."}(int, x=0)
	console(scope(x))
	console(scope{in}(x))
}

example.fn()

n++ example

Examples of scope being used with n++: 

@function(example.fn)
{
	@:={scope+="teji."}(int, x=0)
	@console(@scope(x))
	@console(@scope{in}(x))
}

@example.fn()

@:={private}(int, obj.pair.first, obj.pair.second)
@funcdef{private}(obj.pair.set){}
@funcdef(another.example.func)
{
	@console("current scope: '@scope()'")
}

@console("root scope: '@scope()'")
@console("scope of obj.pair.first: '@scope(obj.pair.first)'")
@console("scope of obj.pair.set: '@scope(obj.pair.set)'")
@another.example.func()

@/*
	expected output:
		root scope: ''
		scope of obj.pair.first: 'obj.pair.'
		scope of obj.pair.set: 'obj.pair.'
		current scope: 'another.example.'
