// ChaiScript supports normal functional programming paradigms, with automatic overload resolution
var plus = `+` // get a reference to the function object representing all known `+` functions
print(plus("a", "b")) // prints "ab"
print(plus(1 , 3)) // prints "4"
// print(plus("a" , 3)) // generates a runtime error, no string + int operator available
// Back ticks are only necessary for capturing operator functions
