proc-macro-hackis sort of a pain to deal with (based on the nested cargo features that were removed by this), and with Rust 1.40 function-like macros can generatemacro_rules!, so this is pretty easy to implement ourselves (proc-macro-hackdoes something with a custom derive on an enum and stringifying and reparsing the input stream).
