     };
    
     sub sub1 {
         meta {
             summary 'This function is for doing blah';
             description 'blah blah ...';
             arg arg1 => (schema => 'int*', req => 1, pos => 0);
             arg arg2 => (schema => [array => of => 'str*']),
         };
         my ($arg1, $arg2) = @_;
         ...
     }

DESCRIPTION

    NOT YET IMPLEMENTED.

    EXPERIMENTAL, SYNTAX *WILL* CHANGE.

    This module is an experiment to provide some syntactic sugar for
    declaring Rinci metadata to your code entities.

    As we know, Rinci metadata is put in %SPEC package variables:

     package YourPackage;
    
     our %SPEC:
    
     $SPEC{':package'} = {
         summary => 'THis package is for doing blah',
         description => 'Blah blah ...',
     };
    
     $SPEC{sub1} = {
         v => 1.1,
         summary => "This function is for doing blah",
         description => 'blah blah ...',
         args => {
             arg1 => { schema => 'int*', req => 1, pos => 0 },
             arg2 => { schema => [array => of => 'str'] },
         },
         args_as => "array",
         result_naked => 1,
     };
     sub sub1 {
         my ($arg1, $arg2) = @_;
         ...
     }
    
     $SPEC{sub2} = { ... }:
     sub sub2 {
         ...
     }
    
     ...
     1;

    This module tries to provide some syntactic sugar.

    How does it work? Using Devel::Declare, it will change the meta():

     sub sub1 {
         meta {
             ...
         };
     }

    to run in BEGIN block (much like how Begin::Declare works). meta() will
    check its caller, if it is inside a sub, it will set subroutine
    metadata. Otherwise, it will set package metadata. The other types of
    metadata will be supported in the future.

    This will not add overhead during runtime, as the BEGIN block will no
    longer be evaluated.

ALTERNATIVE SYNTAXES

 Alternative 1

    Instead of accepting a code block, meta can add a hash where you
    specify the metadata directly. This is easier and all Rinci properties
    are supported.

     sub sub1 {
         meta {
             v => 1.1,
             summary => '...',
             ...
         };
     }
