Arity checks for functions which specify it

[marekjm]

Calls to functions whose names end with /N where N is an integer should be checked for arity match. For example, if a function foo/2 is not called with exactly two arguments it is a compile-time error.

For functions with variable number of parameters, the arity-specifying suffix can be omitted.

[marekjm]

Assembler detects functions whose names end in /N where N is a non-negative integer, and checks if the number of parameters in calls to them conforms to their declared arity. The check if performed only if number of parameters can be detected at compile-time.

Functions without /N suffix in their names are not checked.
