Bug ID: 84769
Summary: variant::get(): unscoped call to get<size_t>
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: duarte at scylladb dot com
Target Milestone: ---
In the implementation of T& get(variant<Types...>& v) and friends, the calls to
the size_t-templated overloads of get is unscoped, like in [1]. This can lead
to surprising situations if a similar function is available in the current
namespace (say, to provide a common interface between <variant> and
<boost/variant.hpp>).
I'm not aware of the standard requiring get() to be an extension point, so
maybe the calls should be scoped?
