+convenient.  Go structs, slices and maps can be automatically converted to Lua
+tables and vice-versa.  The resulting conversion can either be a copy or a
+proxy.  In the latter case, any change made to the result will reflect on the
+source.
+
+Any Go function can be made available to Lua scripts, without having to write
+C-style wrappers.
+
+Luar support cyclic structures (lists, etc.).
+
+User-defined types can be made available to Lua as well: their exported
+methods can be called and usual operations such as indexing or arithmetic can
+be performed.")
