RFC: compiling lpeg into pandoc

[Albert Krewinkel <albert+pandoc-9EawChwDxG8hFhg+JK9F0w@public.gmane.org>]

Hi all,

I'd like to request views and opinions on the inclusion of a Lua library
into pandoc: the LPeg library is a small parsing library written in C to
be used with Lua. http://www.inf.puc-rio.br/~roberto/lpeg/

The motivation is that this library could be used to extend pandoc to
deal with new formats. A good example is jgm's "lunamark", which could
be modified to support custom syntax extensions that might otherwise be
difficult to implement with current filters.
https://github.com/jgm/lunamark/blob/master/lunamark/reader/markdown.lua

On the other hand, this is yet another library and could be considered
bloat. Most users, esp. on Mac and Linux, should not find it too
difficult to install the library on their system should they need it.

The question is therefore if you think whether including lpeg into
pandoc would make is worth it; e.g., do you believe you'd write such
LPeg-based parsers? Would you share them with people who wouldn't
immediately know how to install the library themselves?

Thanks in advance,
Albert
