Kasper Sørensen commented on METAMODEL-61:
------------------------------------------
I prefer you to not subclass but rather compose. Inheritance is anyways only
for situations where something _is a_ instance of the thing it inherits from.
Here I don't think it's the case. Rather it's a _has a_ (or rather _has many_)
relationship so composition is a better choice.

> Right now the CsvDataContext supports reading just a single file and having
> that as a single table. It would be wonderful if you could also instantiate
> CsvDataContext (or some other class) with a folder instead of a file, and
> then have every csv file in the folder show up as a table in the schema. That
> would allow CsvDataContext (or whatever it will be) to be used as a
> functional replacement for almost any other UpdateableDataContext, e.g. for
> testing etc.
