Subject: Parameter passing

Is it possible, to pass local variables by refrerence to method?

I would like to do something like that:

def meth(dest)
  dest = 0 if some_condition
end

...

local_var = 1
# some_condition evaluates to true
meth(local_var)

local_var == 0            # should evaluate to true
