Actually, according to
http://git.savannah.gnu.org/cgit/gsl-shell.git/tree/templates/qag.lua.in?h=gsl-shell-2
Francesco reimplemented quadrature in pure Lua (GSL's C version is
used as a guideline). FFI is used to pass an integrand function
implemented in C to the quadrature routine implemented in pure Lua.
Sort of of the exact opposite to traditional use of scripting
languages.
