My question was not clear -- consider the following example with the 
theoretical function HowWasICalled:

function xxx
    disp(["--> ",HowWasICalled()]);
endfunction

dispatch("yyy","xxx","any");
dispatch("zzz","xxx","any");

xxx
--> xxx

yyy
--> yyy

zzz
--> zzz


Is the a function which does what HowWasICalled does? A function like 
this would allow a single function to be reused. An immediate example 
which springs to mind is a generic warning function:

function gen_warn
    warning("%s is depreciated\n",HowWasICalled());
endfunction

dispatch("set","gen_warn","any");
dispatch("gset","gen_warn","any");


and so on
