torch:fields

(torch:fields module)

The whole fields plist of a module or an optimizer, as a FRESH list: the field names in registration order, each followed by its value. torch:field reads ONE field by name; this is what makes a module tree WALKABLE from outside the package.

nn.Module.apply and nn.Module.named_parameters have no counterpart here because a walk is written over this plist plus torch:module-kind, which says what each layer IS -- more precise than PyTorch's dotted parameter names, where selecting the LayerNorm parameters by testing for 'ln' in the name also selects a layer someone called blend.

The spine is fresh, so consing onto the result cannot corrupt the module; the VALUES are the live parameters and submodules, and the way to replace one is still torch:set-field.
