I'm looking to identify the term for something, what do you call it in kotlin when you invoke a method through the class while passing the this argument explicitly as in (String::take)("hello", 3) or even, what you call the String::take part?

http://kotlinlang.org/docs/reference/reflection.html#function-references
String::take is a function reference to the function take on the class String.

The second parentheses ("hello", 3) is you actually invoking that function you are referencing. Not sure what you mean by passing this in this case.

for example, python would call this an "unbound method" with str.upper, c++ the closest would be "pointer-to-member" with std::string::size

I'm just looking for the name you'd use for String::take in this example, is there not one more specific than it being a function reference?

String::take is function reference, (String::take)("hello", 3) is invoking function by reference (probably) 🙂
