Again, I think this thread clarified we need the "Variant[string] info;"

to use an mighty hyper map capable of holding all informative "values"
will just follow in the same amount of non-using code, and the using

sensless const key-string an still no proper way to show/use the

sorry but feels like throwing anway the signature conecpt and replace it
with an runtime thing ... maybe we should also get rid of function
signatures with "Variant[string] parameter" :}
I understand this seems loose, but again, when you want to do custom
formatting or i18n this is the way to go. The job of rendering the
exception as a string must be outsourced (heh) outside the exception,
and Variant[string] is a simple mechanism to do so.
it does not seem - it is
special_exception --> special_exception_rendere is the way
or else you need to define that clean,compile-time-safe and all the
other stuff isn't needed anymore
