So amusingly I've just had Gob report the following error:

panic: write gob_fetch.txt: host is down

It referring to a file as a host is of course understandable but it's a 
little troublesome because as far as I can tell the file should be 
perfectly writable having just been created and checked for errors on 
os.Create a few lines earlier.
I have a vague memory that there was a package someone major in the Go 
project wrote to create an error stack. I guess this hasn't been ported to 
the whole standard library given the above error.

What's the current thinking on this sort of error handling? It's hard to 
say "Handle errors properly" when the standard library is butchering the 
original error message. Or is there a way to extract the source error 
message that I am missing? [at the moment I'm just doing a panic(err)]

Thanks

Chris
