The main difference between other mail-folder handlers and
Mail::Box is the detail of abstraction, which could simplify
Performance gains are achieved by delay-loading, except when your
application requires all messages anyhow. Then you only benefit
from the C-parser (to be implemented).
Mail::Box prefers messages --which have to be
written to a new folder, for instance when a folder-update takes place--
to be copied byte-by-byte from the source folder. This avoids accidental
changes, and is quite much faster. Only when a message has been modified,
