What is this syntax?

[David Corbin]

def foo(*)
end

What does the "*" mean?

 

[Robert Klemme]

def foo(*)
end

What does the "*" mean?

Any number of arguments

def foo(*) end
nil
foo 1
nil
foo
nil
foo 1,2,3
nil

Kind regards

Any number of arguments

And the foo method just can't refer to them?

Right... I'd assume it's for some kind of case where you're
stubbing something and you want to prevent an undefined
method but you don't really care about the parameters.
