It's a parameter name. ...interface{} is the type of that argument,
variadic in this case indicated by the ellipsis. Argument is for
example the expression 42 in fmt.Printf("%i\n", 42).
Within the body of Printf the 'a' parameter is typed as []interface{}.
These questions are best answered by checking the language
specification: https://golang.org/ref/spec#Function_types and
https://golang.org/ref/spec#Passing_arguments_to_..._parameters
