Nice, Marc; thanks very much.

The implementation of qualified names can be done by checking if the symbol that is read contains a colon.  Note that the handling of qualified names is probably best done by your compiler, so if it was me, I would simply let bar:foo pass through as a single token.

Yes; that's the way the current reader handles all names.

In other words, if the keyword attached to [ ... ] is value-sequence, them [1 2 3] will be read as (value-sequence 1 2 3).

Perfect.

I'll test the code soon and come crying to you if I have any problems. Thanks very much for the help!
