Error messages

["Thiago L." <fakedme@...>]

As you all know, chunks take a chunk name string thingy, and it can be 
"=<whatever>" if you want to customize the chunk name on error messages 
and stuff... What if you could make a function handle error message 
displaying?
Something like...

load(chunk, <stuff>, function(chunkName, lineNumber, errorData, lineData 
stackTraceback) return string.format("%s:%s: 
%s",chunkName,lineNumber+10,errorData) end)

and then the following chunk:

error("my error")

would print:

myChunk:11: my error
<stack traceback stuff>
