OK, thanks. I was actually deliberately avoiding the brackets as I
assumed brackets in regexes are for capturing, and I'm not capturing
anything here.

It does. Thanks. I think I was assuming that all the matches would be
tested and any that apply would be used (rather like omitting to
include a break statement at the end of a case block in a switch
statement in C-like languages). But now I think about it, it doesn't
really make a lot of sense that more than one action could apply for
disposing a message.

Best,
Richard
