real generic?

I would like to do elemental flag and process operations on variables by looping over their fields names (isflagged, adding, ...).

Since eval is evil - this is not possible with the generic functions. For the isFlagged move i use the "match" mode of reindexFlags as a workaround. But for processing tasks i dont know what to use. Did i miss something, or dont we have a solution for that?

Would their be any objections if i implemented something like:

def lambdaGeneric(data, field, flagger, fields, func):
   data[field] = func[data[fields]]
   ...

Maybe just by adding it to the transform.transformation - wich already serves to workaround this shortcoming in the case of single value transformation. Objections? @palmb , @schaefed ?
