The task is to demonstrate the different syntax and semantics provided for calling a function. This may include:
* Calling a function that requires no arguments
* Calling a function with a fixed number of arguments
* Calling a function with [[Optional parameters|optional arguments]]
* Calling a function with a [[Variadic function|variable number of arguments]]
* Calling a function with [[Named parameters|named arguments]]
* Using a function in statement context
* Using a function in [[First-class functions|first-class context]] within an expression
* Obtaining the return value of a function
* Distinguishing built-in functions and user-defined functions
* Distinguishing subroutines and functions
* Stating whether arguments are [[:Category:Parameter passing|passed]] by value or by reference
* Is partial application possible and how

This task is ''not'' about [[Function definition|defining functions]].
