// LUABIND_NO_ERROR_CHECKING
// define this to remove all error checks
// this will improve performance and memory
// footprint.
// if it is defined matchers will only be called on
// overloaded functions, functions that's
// not overloaded will be called directly. The
// parameters on the lua stack are assumed
// to match those of the function.
// exceptions will still be catched when there's
// no error checking.

// LUABIND_NOT_THREADSAFE
// this define will make luabind non-thread safe. That is,
// it will rely on a static variable. You can still have
// multiple lua states and use coroutines, but only
// one of your real threads may run lua code.

// LUABIND_NO_EXCEPTIONS
// this define will disable all usage of try, catch and throw in
// luabind. This will in many cases disable runtime-errors, such
// as invalid casts, when calling lua-functions that fails or
// returns values that cannot be converted by the given policy.
// Luabind requires that no function called directly or indirectly
// by luabind throws an exception (throwing exceptions through
// C code has undefined behavior, lua is written in C).
