On: And, Why Didn't Dijkstra Like Lisp?

[ekiru]

I don't think that that is true, at least not for Common Lisp.

How do you express any of the following constructs using only parentheses and symbols?

#:foo #.(foo) #+ FOO (bar) #- FOO (baz)

For the original Lisp, parentheses and symbols were all that was necessary. For more recent derivatives, that is not necessarily the case.

[astine → ekiru]

Well, Packages are a reader-hack, so you couldn't express them with parenthesis, although you should be able to IMHO.

#+FOO (bar)

This could almost be: (when (member FOO features) (bar)) Just wrap it in an eval-when.
