Back for a Christmas visit this year. Since Christmas is the long summer 
holiday here, I'm hoping to be over for a while: certainly long enough to 
attend (or possibly cause!) a social.

True - but as long as magic variables are global, you do need local, and you 
never know when else you might need it: one should probably also know why one 
probably won't need it.

There's an old joke about a rockstar going to buy a Rolls-Royce: he queries 
the presence of a toolkit in the boot, saying, "I thought you told me this 
thing was reliable". The salesman's response:
"Do you have nipples, Sir?"
"Yes."
"And are you ever likely to breast-feed?"
"Don't be stupid."
"Quite, Sir: but they *are* there - Just In Case."

local is there Just In Case.
