IMHO, you're comparing apples and oranges. There is a major difference between clients and users. Programs are not "users". They are "clients". They have a well-defined, well-formed, and limited usage of a supplier's capabilities. They are trusted.

People, on the other hand, are "users". They are not well-defined, well-formed, nor are they limited in their capability to err. Programs that deal with "users" must take this into account. (The exception is administrator-type "users", which are trusted, so they can be considered "clients".)

I don't think that suggesting eval here without knowing more about what the OP wants to do is valid. It turns out that the OP's need is better served through other means. eval, imho, is meant for two situations:

  1. Quick'n'dirty hacking on a problem in a one-off situation
  2. Situations where there simply is not any other method of solving the problem

It doesn't appear that either situation applies here.
