impressive. thanks!!!

$ cat test_guard.lua

local guard = require ("guard")

function isError( data )
if (data.errno < 0) then return true; end
end

function isOk( data )
if (data.errno == 0) then return true; end
end

function default_callback(data) return data.message end

function ok_callback( data )
return data.message;
end

function error_callback( data )
-- logger
return data.message;
end

g = guard()
.when(isOk, ok_callback)
.when(isError, error_callback)
.any(default_callback);

print( _VERSION )

print( g({errno=0, message='ok'}) );
print( g({errno=-1, message='general failure'}) );
print( g({errno=1, message='warning...'}) );
