I think this would be very convenient for extension development.

`dirname`on all the entires in DATA and MODULES to figure out what to put in the search paths. I usually have my C

worse).A simple example is the envvar extension[2]:

Interesting.  I think to support that, we would need to do a temp 
install kind of thing of the extension, and then point the path settings 
into that temp install directory.  Which is probably more sensible anyway.
