warning: unused attribute `macro_export`

   |
43 |     #[macro_export]
   |     ^^^^^^^^^^^^^^^
   |
note: the built-in attribute `macro_export` will be ignored, since it's applied to the macro invocation `thread_local`
  --> src/main.rs:44:5

   = note: `#[warn(unused_variables)]` on by default
   = note: this warning originates in the macro `input_internal` which comes from the expansion of the macro `inputv` (in Nightly builds, run with -Z macro-backtrace for more info)
