-%   String comparisons rely on the primitive \cs[index=pdfstrcmp]{(pdf)strcmp} if available:
-%   \LuaTeX{} does not have it, so emulation is required. As the net result
-%   is that we do not \emph{always} use the primitive, the correct approach
-%   is to wrap up in a function with defined behaviour. That's done by
-%   providing a wrapper and then redefining in the \LuaTeX{} case. Note that
-%   the necessary Lua code is loaded in \pkg{l3boostrap}.
-%   The need to detokenize and force
-%   expansion of input arises from the case where a |#| token is used in the
-%   input, \emph{e.g.}~|\__str_if_eq:nn {#} { \tl_to_str:n {#} }|, which
-%   otherwise would fail as \cs{tex_luaescapestring:D} does not double
-%   such tokens.
+%   String comparisons rely on the primitive \cs[index=pdfstrcmp]{(pdf)strcmp},
+%   so we define a new name for it.
