Status: Ready for review

Fix #5092

Introduce a new macro in frame-support which discard content if try-runtime is not enabled.

Use this macro inside frame-support-procedural to generate code only when frame-support is compiled with try-runtime.

I believe this is not a breaking change. Should I include a prdoc?

is it? frame imports frame-support with try-runtime feature so frame-support-procedural should also have try-runtime feature.

proc_macro2::TokenStream::new()
};

let try_state = if cfg!(feature = "try-runtime") {

We should not do this. This is partly "cursed". Sometimes this is not really working well.

You can create a macro in frame_support using this macro and then you can use this to guard the code. Here is an example of what I mean.

Fix paritytech#5092

Introduce a new macro in frame-support which discard content if
`try-runtime` is not enabled.

Use this macro inside `frame-support-procedural` to generate code only
when `frame-support` is compiled with `try-runtime`.
