Cryptic errors for top-level let statements.

[LouisGariepy]

Versions

rust-analyzer: v0.4.1539
rustc: 1.70.0

Reproducer

Simply write a top-level let statement.

let x = 1;

Explanation

Hovering the let keyword gives

Syntax Error: expected an itemrust-analyzer syntax-error
expected item, found keyword let
consider using const or static instead of let for global variables

Hovering the whitespace between let and x

Syntax Error: expected an item rust-analyzer syntax-error
expected item, found keyword let
consider using const or static instead of let for global variables
Syntax Error: expected BANG rust-analyzer syntax-error
Syntax Error: expected {, [, ( rust-analyzer syntax-error
Syntax Error: expected SEMICOLON rust-analyzer syntax-error

Hovering x gives

Syntax Error: expected BANG rust-analyzer syntax-error
Syntax Error: expected {, [, ( rust-analyzer syntax-error
Syntax Error: expected SEMICOLON rust-analyzer syntax-error

Likewise, hovering the rest of parts of the statement gives similar yet slightly different messages.

As you can see, some of those messages are surprising.

The red underline squiggles are also a bit surprising:

What I expected

I expected the whole statement to be underlined consistently, and the hover message to only contain the relevant error message (i.e. the one that you get when hovering the let keyword, see section above).
