Description:

the new RETNIL and RETDEF macros are throwing errors if the value is not defined (only sheduled environment)

_apple = nil;
_juice = [_apple] param [0]; // throws error

old version:

_cherry = nil;
_juice = If (isNil{_cherry}) then {nil}else{_cherry}; // no error

[Dorbedo]

Possible fix ? :

#define RETDEF(VARIABLE,DEFAULT_VALUE) ([VARIABLE,DEFAULT_VALUE] select isNil{VARIABLE})
#define RETNIL(VARIABLE) ([VARIABLE,nil] select isNil{VARIABLE})

^ would error too

[commy2]

my proposal:

#define RETDEF(VAR,DEF) (if (isNil QUOTE(VAR)) then [{DEF}, {VAR}])
#define RETNIL(VAR) RETDEF(VAR,nil)

[commy2]

should also add some unit tests for these, so they are not broken again in future

Why use that syntax commy, the normal if-else syntax doesn't error either.

Just a command less, doesn't make much difference.
