Loads the smallest possible set of modules for PDL to work, importing only those functions always defined by PDL::Core) into the current namespace ("pdl", "piddle", "barf" and "null"). This is the absolute minimum set for PDL.
Access to other functions is by method syntax, viz:
$x = PDL->pdl(1, 2, 3, 4, 5); $x->wibble(42);
use PDL::Lite; # Is equivalent to the following: use PDL::Core ''; use PDL::Ops ''; use PDL::Primitive ''; use PDL::Ufunc ''; use PDL::Basic ''; use PDL::Slices ''; use PDL::Bad ''; use PDL::Version; use PDL::Lvalue;
