This are the hooks that I change in structured_text.sl:

   set_buffer_hook("wrap_hook", &st_indent);
   set_buffer_hook("indent_hook", &st_indent);
   set_buffer_hook("backward_paragraph_hook", &st_backward_paragraph);
   set_buffer_hook("mark_paragraph_hook", "st_mark_paragraph");
   set_buffer_hook("format_paragraph_hook", "st_format_paragraph");
   set_buffer_hook("newline_indent_hook", &st_newline_and_indent);
   set_buffer_hook("par_sep", &st_is_paragraph_separator);

But you are right, only the format_paragraph_hook is needed to let the
default format_paragraph binding execute your latex->format_paragraph()
function. The remainder is to make "smart" the move-by-paragraph, the
wrapping, and the indention features.

The parse_to_point() internal function is fast.
Some caching in the indent_hook might help, if getting the remaining
info is still too slow.

Yes, this is the simple way to define a mode-specific format-paragraph
function without bothering about the keybinding.
