The error message is certainly better now in alpha-rc1, but is there a
way to call debug.getuservalue on an unknown userdata without
potentially raising an argument error? Can I identify light userdata in
pure Lua? I can live with pcalling getuservalue, but it seems strange...
debug.getfenv in Lua 5.1 returned nil for light userdata.
