What about this?

rust/src/libsyntax/parse/token.rs

Lines 147 to 157 in 4be0675

	pub(crate) fn ident_can_begin_expr(name: ast::Name, span: Span, is_raw: bool) -> bool {
	let ident_token = Token::new(Ident(name, is_raw), span);
	!ident_token.is_reserved_ident() ||
	ident_token.is_path_segment_keyword() ||
	[
	kw::Async,
	// FIXME: remove when `await!(..)` syntax is removed
	// https://github.com/rust-lang/rust/issues/60610
	kw::Await,

Hm, that seems to be a language change, in particular based on the name would allow for example await.foo to be used, which we might not want? I'll defer to @Centril on whether to remove it.

Thanks! @bors r+ rollup

PS: Is there some tool we can use to shake out dead code that happens to use pub? -- there's probably more in the codebase that could be thrown out that way.

@lzutao I think we could try removing that in a follow up; we'll need a test to demonstrate that await.foo will still not parse.
