I've just read my first James Bond novel, Casino Royale. In it, I have found several instances of the word "directly" being used in a way I am not familiar with. It appears to have the meaning "when" or "right after" or "as soon as":
"Directly the cards were dealt I kicked myself."
Directly Bond and Leiter had left to walk over to the hotel, she had telephoned.
Directly the boot was shut, the third man [...] climbed in beside him [...].
Directly they sat down, he apologized gaily for having startled her at the telephone booth [...].
Is this an obsolete used of the word? Is this only British English? I have read quite a lot of books from many different time periods, but I've never stumbled across this before - do other authors besides Fleming use "directly" in this way?
