Hi Piter,

Life is good, thanks.  Glad to see you're still in action.  Are you
still maintaining the batch script to build QuantLibXL?

I don't remember the discussion and can't find any mention of it in
the archives.  But looking at it now I see the problem, that the
constructor of the Business252 class expects an input argument.  This
is not supported by the design for enumerated datatypes.  The user
supplies a string e.g. "Actual/360" and the system automatically calls
the default constructor of the corresponding class e.g.
QuantLib::Actual360().  There is no mechanism for an argument to be
supplied to the constructor.

Could the class be reworked to support a default constructor?  If not,
perhaps we could expose it as a proper stateful object.

Thanks,
Eric
