@pitrou Hi，I have a question regarding this issue and I want to ask for your
advice.
In this code, because field is a function with default parameters, one can
pass not only name and type to this function, but also nullable and metadata
``` struct_({field("a", int8()), field("b", utf8())}); ```
but in the following form, I can use
std::initializer_list<std::pair<std::string, std::shared_ptr<DataType>>> as the
input parameter, but in this way it's hard to add support for passing in
nullable and metadata inconveniently like the field function. std::tuple
doesn't support default parameters too.
``` struct_({{"a", int8()}, {"b", utf8()}}); ```
I guess there is a better way to write this overload function or shall we
just support (name, type) pairs for now?
Thanks for your time.
