-/** @brief Print a Cubescript stack
- *
- * This prints out the Cubescript stack as stored in cubescript::error, into
- * the `writer`. Each level is written on its own line. The line starts with
- * two spaces. If there is a gap in the stack and we've reached index 1,
- * the two spaces are followed with two periods. Following that is the index
- * followed by a right parenthesis, a space, and the name of the ident.
- *
- * The last line is not terminated with a newline.
- *
- * @return `writer` after writing into it
