/* Limitations of overloaded operators compared to regular function calls:
* 1. at least one operand must be a class, so cannot just write `ch in "abc"` 
*    (possible solution: ch in "abc"_s)
* 2. operand cannot be initializer list (exception: assignment ops), so cannot just write `ch in {'a','b','c'}` 
*    (possible solution: ch in ${'a','b','c'})
