You can raise errors on any Lua value, not just strings.
(This much has been true for a long time.)
What is new is that the standalone interpreter now respects __tostring:
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
> error(io.stdin)
(error object is not a string)
Lua 5.2.0 (work1) Copyright (C) 1994-2008 Lua.org, PUC-Rio
> error(io.stdin)
file (0xe8b420)
