// Variable Arguments Script in Squirrel 2.2
// Tested with Raw Squirrel - Video tutorial: https://youtu.be/GnNkZliWOQk

/*

	Key notes:
	
	vargc - Holds the length for the pseudo-array (variable argument)
	vargv[i] - Access the individual index where i is the index to look at/for
	
	Variable Arguments in Squirrel are denoted as 3 dots (...), which should be at the last in the argument/parameters
	
	VALID: function DoSmth(name, age, ...)
	INVALID: function DoSmth(..., name, age)
	
	Squirrel cannot tell at runtime how long (in theory) the vararg could be, this is why it is declared at the end
