I know ;-) But the previous posts basically asserted that without some substitution, it wasn't possible to do this. When using this technique, you'll want to turn on taint checking and thus be forced to inspect the input (the TEXT=... in this case). But while doing that, it's probably easier to make the substitution right away, thereby removing the need for the eval altogether!

Sometimes, using this technique (or the do EXPR function) is useful for writing a script which uses a configuration file without using a special module for it. It's just another way of doing something, and can be very convenient sometimes.
