Re^2: Params::Validate or Attribute::Params::Validate?

[diotalevi]

In Regexp::NamedCaptures, I wrote this snippet so that P::V would be used if it was available and dummied up into place if it wasn't. I have half a mind to make that become a P::V::Fake and just include that with the distribution tarballs of my modules. My Build.PL recommends P::V and my Makefile.PL is silent on the matter.

BEGIN {
    eval {
    require Params::Validate;
    Params::Validate->import( 'validate_pos',
                  'SCALAR',
                  'UNDEF',
                  'CODEREF' );
    };
    
    if ( $@ ) {
    eval( 'sub validate_pos (\@@) { @{$_[0]} }'
          . 'sub SCALAR () { 0 }'
          . 'sub UNDEF () { 0 }'
          . 'sub CODEREF () { 0 }' );
    }
}
