You could overload class methods as long as they had different signatures.  
ooeu mangled names similar to C++.  So you could have two different methods
with the same name and same number of parameters.  The return type helped
the parser figure out which method to use based upon the return parameters
from functions.  It wasn't enforced in ooeu.

euclass complex( sequence c )
    atom real, imaginary
    
    function add( atom a ) : complex
        ...
    end function

    function add( complex c )
        ... 
    end function

    function complex( atom r ) : complex
        return {r, 0}
    end function

    function complex( atom r, atom i ) : complex
        return {r, i}
    end function

    function complex( complex c ) : complex
        return c
    end function
end euclass

complex x, y
x = complex( 0 )
y = complex( 5, 2 )

x = x.add( 3 )
x = x.add( y )
x = x.add( y.add( 2 ) )
