Hello, A "philosophy" question. For storing values that will be used "as is", normally one would do \def\storesomething{Something}. In the LaTeX3 model, I can choose either \def:NNn \store_something: 0 {Something} or \tlp_new:N \l_store_something_tlp \tlp_set:Nn \l_store_something_tlp {Something} and get the same result, function-wise. Is the later closer to the model proposed, or should I stick with the former? -- Joseph Wright
