fields
Pragma that provides the ability to define class fields
at compile time by updating the %FIELDS hash in the calling package. The
%FIELDS hash is set up at compile
time as well; use the base pragma
to copy fields from base classes, and then fields to add new fields. Lets you have
objects with named fields that are as compact and fast as arrays to
access. For more details, see the fields manpage
and the pseudo-hash section of the perlref
manpage.
