---------------------------------------------------------------------- 
I have gone ahead and reproduced this issue. It appears to be an AEL thing,
and not a func_cut thing -- although it could actually be CUT() not
accepting or understanding the commas in the dialplan. Here is my
extensions.ael and extensions.conf files:

extensions.ael:

macro test (abc,cba)
{
        NoOp(${cba});
};

context 13416 {
        100 => {
                &test("testing",${CUT(EXTEN,,3)});
        };

        101 => {
                res=${CUT(EXTEN,,3)};
                &test("testing",${res});
        };
};


extensions.conf:

[13416-conf]
exten => 102,1,Set(res=$[${CUT(EXTEN,,3)}])
exten => 102,n,Macro(test,"testing",${res})



And here is the output of 'show dialplan':

  '102' =>          1. Set(res=$[${CUT(EXTEN||3)}])              
[pbx_config]
                    2. Macro(test|"testing"|${res})              
[pbx_config]

[ Context '13416' created by 'pbx_ael' ]
  '100' =>          1. Macro(test|"testing"|${CUT(EXTEN,,3)})   
[pbx_ael]
  '101' =>          1. Set(res=$[${CUT(EXTEN,,3)}])             
[pbx_ael]
                    2. Macro(test|"testing"|${res})              
[pbx_ael]

[ Context 'macro-test' created by 'pbx_ael' ]
  's' =>            1. Set(abc=${ARG1})                          
[pbx_ael]
                    2. Set(cba=${ARG2})                          
[pbx_ael]
                    3. NoOp(${cba})                              
[pbx_ael]



I even tried putting in the hyphen in CUT() to see if that helped, but
still got the same error.

I notice that in 'show dialplan' the commas show up in the pbx_ael lines,
but in pbx_config they are converted to pipes (as per 1.4 style) -- so
maybe that has something to do with it?

Or... this could also be a syntax issue in AEL. I'm not sure about that as
I haven't really used AEL much (this was actually my first time in a couple
years :))
