Thanks. I'll pick up on those when I finally get round to looking at
this. The only thought I have had was: WHY? That is, why would anybody
use a "switch group", specifically asking for different groups to have
the same numbers, and then want to give them different names? One brutal
approach might simply be to forbid this. In other words, specify that if
several groups have the same number, they must have the same name as
well. (PCRE does permit groups with the same name to have different
numbers, however.)
Regards,
Philip
