generate_namespace_generator filtering necessary symbols

[phillip-martin]

First of all, I just want to say that I've found the script gnerate_namespace_generator to be very helpful in my own work. So thank you for providing it in the nimbus repo.

I also appreciate that the filters are documented (e.g. grep -v "\$_NS" on line 43). This makes it very clear what symbols the script wants to avoid adding to the namespace header file. Only one filter, grep -v ".eh" (on line 71) is undocumented (as far as I could find).

The only reason I discovered this was that this script (or I should say a slightly modified version of it), was filtering out symbols like "filehandle", which matches ".eh". I assume this wasn't the intended behavior of the filter but I also assume that it was included for a good reason. Does anyone know the original intent of grep -v ".eh" in this situation?

This would be hugely helpful, and I appreciate any feedback.
