Yeah, I thought of that, but Bro currently doesn't have any '&' or '|'
operators, which makes me reluctant to add them just for this. '&' is
particularly problematic, as it would introduce ambiguity as to whether
"&redef" means the redef attribute, or "use the 'and' operator on the value
of the variable 'redef'". We'd have to add a bunch of reserved words
to accommodate this.

(same here re being a new operator)
