Tuple

$(D_PSYMBOL Tuple) can store two or more heterogeneous objects.

The objects can by accessed by index as obj[0] and obj[1] or by optional names (e.g. obj.first).

Specs contains a list of object types and names. First comes the object type, then an optional string containing the name. If you want the object be accessible only by its index (0 or 1), just skip the name.

Specs...

) {

template parseSpecs(size_t fieldCount, Specs...);

alias ChooseType(alias T) = T.Seq[0];
