actionscript - Getting the source code of a function? -

is there anyway can code inside function in actionscript (preferably as1)?

for example, let's have function:

function foo(){     trace("bar"); }

is there anyway can text 'trace("bar");' function without modifying actual function?

like (psuedo code):

trace(foo.source);

would trace text 'trace("bar");'
