Inherited attributes and copy() function

[Öyvind Strand <oyvind.strand@…>]

rule::copy() and rule::alias() functions doesn't work when used on rules with inherited attributes.

using namespace boost::spirit::qi;

typedef std::string::iterator iter;

rule<iter, int()> a; rule<iter, int()> a_cp; a_cp = a; compiles a_cp = a.copy(); compiles a_cp = a.alias(); compiles

rule<iter, int(int)> b; rule<iter, int(int)> b_cp; b_cp = b; compiles b_cp = b.copy(); fails to compile b_cp = b.alias(); fails to compile

Has it been attempted to address this issue? It seems rather fundamental.
