Operator Overloading - language feature

Example from 1 languages: Python

# Python Program illustrate how
# to overload an binary + operator
  
class A:
    def __init__(self, a):
        self.a = a
  
    # adding two objects
    def __add__(self, o):
        return self.a + o.a
ob1 = A(1)
ob2 = A(2)
ob3 = A("Geeks")
ob4 = A("For")
  
print(ob1 + ob2)
print(ob3 + ob4)

Example from 1 languages: Speedie

str = "a" + "b"
array <~ str

Example from 1 languages: C3

fn int IntList.get(IntList* this, int idx) @operator([])
