Thank you!

Understood.  We have worked to remove all Evals as low performance,
and as  "debugger unfriendly".

A work-around comes to mind using a couchDB type "document base" using
Jason that would seem to be faster and less dangerous. Are there any
of these types of document bases "approved" for Heroku?   I see only
Amazon RDS mentioned directly.

The unique part of each class is a single method.  This method could
be overwritten using a the define_singleton_method (as best I
remember).
This would only be in memory, but would seem to be a fast and
otherwise clean work-around (assuming of course the that text can be
safely stored somewhere)

(The text file being written would also be lost under circumstances.)

BTW I tried marshaling the object with Singleton methods to files -
and Ruby will not like this :) - but the pickAx book points out a way
to do it as I remember.

This all seems more involved than it should be.

Are there, perhaps,  Heroku "semi-commercial" programs available where
this is not a problem?

Is this all for security reasons?
