An idea for this is to use define_method + copy_captured_locals which is basically a way to embed constants (in this case the Symbols of the Struct attributes) in the generated method.

However that doesn't allow to unroll the loop (+ specialize for each attribute) easily. One way is to have the define_method itself in an class_eval, then we can generate code from Strings + reference constants.
