lambda's

Hi,

The return value from a lambda gets "int'ified" so I am not able to distinguish a "return 0;" from a "return UNDEFINED;".

I guess it's not too hard to fix, but might break something?

Is there a workaround.. what can I do?

Ex: Pike v7.7 release 9 running Hilfe v3.5 (Incremental Pike Frontend)

function a = lambda( int b ){ if( b > 0 ) return b-1; if( b == 0 )

return UNDEFINED; };

a(2);

(2) Result: 1

a(1);

(3) Result: 0

zero_type(_);

(4) Result: 0

a(0);

(5) Result: 0

zero_type(_);

(6) Result: 0 // would like zero_type to return 1 here!

a(-1);

(7) Result: 0

zero_type(_);

(8) Result: 0 // I expected UNDEFINED, since nothing was

	// returned from the lambda..
