Hello,

first of all: I stand in awe watching this discussion I've inadvertently
started.

BTW: I think you nailed a serious problem with contemporary mathematics:
that machine checking proofs isn't a routine part of the publishing
process.  The number of erroneous papers in math journals is
horrifying.  Substantial portion of my depatment's seminar is devoted to
discussing errors in papers.  Once a colleague found a relatively simple
/counterexample/ to a theorem which was a cornerstone of a whole theory
(and a basis for several dozen other papers).
