Loads the smallest possible set of modules for PDL to work, making the functions available in the current namespace. If you want something even smaller see the PDL::Lite module.
use PDL::LiteF; # 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;
