`relm4_macros::view!` triggers `clippy::used_underscore_binding` lint. about relm4 HOT 2 CLOSED

Thanks for the report!
I wasn't really aware of the differences between call site and mixed site so far despite writing thousands of lines of proc-macro code. Should be relatively easy to fix, probably most Ident::new calls simply have to be adjusted.

from relm4.

I've checked most invocations of quote! and quote_spanned! and the macro hygiene isn't to great in some places. Changing the span of most idents, I've found several places where identifiers such as __current_page and similar are created or used in an invocation of quote_spanned!. This makes those identifiers assume the provided span which in some places is a call site span. These kind of identifiers should really be created outside of the quote_spanned invocation and be given a mixed site span.

Rust macros really shouldn't need the C-style underscore prefixes, proper use of Span should take care of name conflicts.
