Object type check

[king kikapu]

at first, thanks you all for your help!

So, i will follow your advice.In a moment though, i thought that "ok,
do not check anything of the parameter's type but do a try/catch at
the calls inside the function"

But this way, i would rather defeat the purpose because i have to try/
catch in *every* call inside the func.
So, i suppose that i wouldn't want to do that and just try to make the
call in whatever they passed me in.

Strange world the dynamic one....
