=head1 NAME
Test::Deep::PDL - Test piddles inside data structures with Test::Deep
=head1 VERSION
version 0.12
=head1 DESCRIPTION
This is just an implementation class. Look at the documentation for test_pdl()
in L<Test::PDL>.
=for Pod::Coverage init descend diag_message renderExp renderGot
=head1 BUGS
The implementation of this class depends on undocumented subroutines in
L<Test::Deep>. This may break if L<Test::Deep> gets refactored.
