Currently creating named tuples is a bit wordy: Tuple!(double, "x", double, "y")(1.0, 2.0); This could be simplified by adding a namedTuple function: namedTuple!("x", "y")(1.0, 2.0); I have an implementation in ggplotd (named aes [1]), which could be used if people think this is a good idea.

We already have a function that does this in std.typecons: auto t = tuple!("x","y")(1.0,2.0); https://dlang.org/phobos/std_typecons.html#.tuple

Never even considered that tuple! might be able to do this. Sorry for the noise :)
