I noticed two things with %prefix when combined

(1) %prefix=abc renames function yylex to "abclex"

You are right, it should be in a namespace, though I think it might
have been left so, i order to sync with Flex. I think one might put
it in a namespace, but have another option, say %lexer-prefix, which
if present, writes it in the global form.
(2) Nested namespaces do not work:
%prefix=abc::def should give
namespace abc {
namespace def {
..
}
}
instead of
namespace abc::def {
..
}
I guess?
This is due to a bug in the C++ standard, but they seem unlikely to
fix things like that there :-). So it should probably write nested
namespaces, or not admitting "::" in the name.
Is this known and planned to fix?
Don't know; I have cc-ed some Bison developers.
