Subject: globals outside of OO scripting

When writing methods as functions (I know they're methods pretending to 
be functions) do you still need to use globals... like this:

$global_var
def some_other_function
    ...
    $global_var
end

Or, is it OK to use them like this:

global_var
def some_other_function
    ...
    global_var
end
