Re: [isabelle] Lawrence Paulson's 60th Birthday today

Dear Larry,

Happy Birthday! Let me add just one more "not to mention" to the growing (lazy) list: the first mechanical verification of possibly the most influential result in modern logic, Godel's second.

Dear Larry,

Also from me many congratulations on your birthday!  And my
thanks for creating Isabelle as well.

(When I started being interested in formalizing classical
mathematics, Randy Pollack told me that Isabelle was _the_
system I should have a look at.  He was absolutely right.)
