Re: st: passing argument(s) to Mata constructors

Thanks.  Alternatively, you can use a factory function that takes
arguments, and returns a fresh instance of the class suitably
initialized (i.e., based on the arguments passed to it).  That's what
I wound up doing in this case.

Good that you could find a workaround for your situation.  A simple
factory is handy, but it really doesn't give you what the ability of
a constructor to take arguments does.  There are situations where a
simple factory can't serve as an alternative to passing arguments to
constructors, for example, try implementing a singleton design
pattern in Mata (not that typical Mata usage needs a singleton).
