Functions in Limbo are similar to functions in Go moreso than functions in C.
This section shows a function prototype as well as the succeeding function definition. Prototypes in Limbo function similar to prototypes in C.
The function plus() takes two integers as arguments and returns their sum.
The function swp() takes two integer arguments and returns two integers within a tuple.
Note that the type statement : int is only provided once, with the list of variables to the left of the type statement being declared to be integers.
The function plusplus() takes three integer arguments and returns their sum, calling the function plus() in the process to sum the first two arguments.
The return value of plus() is a single variable, so it can be added to c without any extra syntactical structures than using the return value as an unnamed variable.

3 + 5 = 8
7 + 3 + 4 = 14
swap 6,7: 7,6
;
- Try returning more than two values, can tuples store more than two ordered objects?
