Everything is possible, but his will require you to supply meta data on your
function when setting it, which is quite a lot of extra work when creating
your function. The current method uses Function.length, which is a built in
feature in JS - which meant no extra syntax for it to work. Your request
would have to be something like:
Object.overload(obj,'name',[
{ fnc : function(a,b,c){....}, args: [ 'sting','number','string' ] }
, .....
]);
this will also mean that every check will need to check for Function.length,
then iterate on arguments ( I guess serializing can make this simpler, but
it's still a lot of overhead)
IMO - imposing strict typing on a dynamic type language like JS is a bad
idea - aside from the overhead of type checking on every parameter every
time the function is called, this also introduces a lot of confusion for
people who use the Class, as no one expects his code to be strict typed.
I am however interested in making something like this, so I might take it up
for a weekend fun coding
