in thread Params::Validate or Attribute::Params::Validate?

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 }' ); } }
