save snippet in local variable?

[IcyAlmond]

local parameter_choices = {
  ls.snippet(1, {
    ls.insert_node(1),
    ls.text_node(", "),
    ls.insert_node(2),
  }),
  ls.snippet(2, {
    ls.insert_node(1),
    ls.text_node(", "),
    ls.insert_node(2),
    ls.text_node(", "),
    ls.insert_node(3),
  }),
  ls.snippet(3, {
    ls.insert_node(1),
    ls.text_node(", "),
    ls.insert_node(2),
    ls.text_node(", "),
    ls.insert_node(3),
    ls.text_node(", "),
    ls.insert_node(4),
  })
}
ls.add_snippets("all", {
  ls.snippet("func", {
    t("function "), i(1, "functionName"), t("("), c(2, parameter_choices), t("): ")
  })
})

How can I save and reuse snippets like that? Right now, it gives this error:

...share/nvim/lazy/LuaSnip/lua/luasnip/nodes/snippet.lua:193: attempt to index local 'context' (a number value)

Mhmm, in this case you'd have to store a list of snippetNodes, instead of snippets.
And, if these are passed into multiple snippets, use vim.deepcopy (or snippetNode:copy(), which should be preferred, but is more unwieldly when copying lists of nodes) at each copy-site.

But what's your final goal with this? Maybe there's a more idiomatic way of achieving it :)
