Ah. I thought you were talking about a lazy evaluation parser.
I don't think you are going to find any measurable savings in deferring much,
if any, of the header parsing, even into complimentary formats. The
measurements I did in the Cyrus IMAP server's MIME parser showed that that part
of the code was in the noise compared to the I/O overhead.
We were optimizing for response time across hundreds of transactions per
second. I can't imagine how anyone using MH from the command line would ever
notice this sort of tune-up.
I'm all in favour of cleaning up the code, but let's not drive the process from
a false premise.
