Is the "Churchill slash" actually standard practice?
I've been reading Playwriting by Stephen Jeffreys, which contained (among lots of other excellent information) the following:
>Caryl Churchill introduced the standard typography for interrupted dialogue in plays. She uses a ‘/’ – the ‘Churchill slash’ – to indicate when a line of dialogue should be interrupted by the next line.
On the one hand, it sound very useful as a tool for writing dialogue. On the other, I've never seen a Churchill slash in any of the plays I've read (which, yes, is a smaller number than I'd like it to be). I'm not self-taught per se but there's still a lot I need to learn about standard conventions in the playwriting world. Can I expect people to understand what it means, or would they sooner assume that the "/" is a typo?
