Hallo

from my Point of view there is an unexpected behavior using named Parameter inside a class.

To make this clear i wrote some example-code:

--optional/named Parameter 
--Phix 1.0.4 64bit Win10 
    function adc(integer x,integer y) 
    return x+y 
    end function 
 
?adc       -- unexpected result no crash/why? 
--?adc()       -- crash with missing parameters expected 
?adc(2,2)  -- works 
--?adc(x:=2) -- crash expected 
 
    function add(integer x=1,integer y=1) 
    return x+y 
    end function 
?add       -- unexpected result no crash/why? 
?add()     -- works 
?add(2,2)  -- works 
?add(x:=2) -- works 
 
class two 
    function add(integer x=1,integer y=1) 
    return x+y 
    end function 
end class 
 
two addfunc=new() 
 
?addfunc.add   --unexpected result no crash/why? 
?addfunc.add() --works 
?addfunc.add(2,2) --works 
--?addfunc.add(x:=2) --crash with undefined identifier x unexpected 
 
 
wait_key() 

Thank you
