I have some questions regarding using set-default to set buffer local
variables when changing major modes.

(1) when a major mode is started, I believe that kill-all-local-variables is
    called. Is it true that all buffer local variables then revert to their
    default values?

(2) can one define a default value for a variable to be the result of a
    conditional? for example,

    (setq-default this-is-my-variable
		  (if table-tennis (foobar) '("%b")))

    where `foobar' returns a string.  does this set the value of
    `this-is-my-variable' to the string returned by `foobar' or to "%b" based
    on the value of `table-tennis'?

(3) finally, would the above setq-default be evaluated each time a new major
    mode is started?

thanks in advance. please respond via e-mail. if there is much interest I will
post a summary.
