YATT::Lite::MFields -- fields for multiple inheritance.
# Like fields.pm use YATT::Lite::MFields qw/foo bar baz/; # Or more descriptive (but these attributes are for documentation only) use YATT::Lite::MFields ([name => is => 'ro', doc => "Name of the user"] , [age => is => 'rw', doc => "Age of the user"] ); # Or, more procedural way. use YATT::Lite::MFields sub { my ($meta) = @_; $meta->has(name => is => 'ro', doc => "Name of the user"); $meta->has(age => is => 'rw', doc => "Age of the user"); };
This module manipulates caller's %FIELDS hash at compile time so that caller can detect field-name error at compile time. Traditionally this is done by fields module. But it explicitly prohibits multiple inheritance.

Yes, avoiding care-less use of multiple inheritance is important. But if used correctly, multi-inheritance is good tool to make your program being modular.
