Let's assume that we want to pass function goo as argument
to another function foo and extract list of arguments
of the function goo:
foo[fun_] := Module[{argList}, argList = Table[fun[[i]],{i,1,2}] ]
foo[goo[x,y]];
This will result in list:
{x,y}
But if goo was defined before eg:
goo[s_,t_] = s^2 + t^3;
then we get:
{x^2,y^3} .....
Can anybody point me in a right direction here?
Sorry for such an elementary question...
