xpcall does not handle ERRERR how it should.
The error handler for the error handler is itself; not the upper scope
as you would imagine.

a=function() error("a") end
b=function(e) print("b",e) end
xpcall(a,b)

This bug stops you from being able to bubble up errors.

a = function() error{type="foo"} end
xpcall(a,function(err) if err.type == "bar" then else error(err) end end)

==> you'd imagine that the error in the error handler would re-throw the error.

Daurn.
