Bytestrings

The code for the hexadecimal value FE should be \xfe.
The code shown (\0xfe) is actually the octal value 0 followed by the characters 'x', 'f' and 'e'.

Note from the Author or Editor:
Reporter's description is correct. Script needs to omit the zero digit from the string "\0xfe"

Decorators

Why do method calls to both wag() and sniff() output the print statement in wag()? Seems like the decorator has messed up something there.

Note from the Author or Editor:
This occurs because of a complicated issue involving the re-use of a local variable. I will publish a blog entry to explain the issue with the existing code before correcting it.

The bog entry (which also contains the germ of the fix) is at http://holdenweb.blogspot.co.uk/2014/07/closures-arent-easy.html for those who want the gory details.
