Incorrect this block is empty, you might have not meant to close it on any channel

[olegnn]

Any code which has correct () and incorrect braces like f) after them will produce incorrect this block is empty, you might have not meant to close it which will point at the valid parentheses. This behaviour is the same on all channels.

fn main() {}

fn f) {}

(Playground)

Errors:

   Compiling playground v0.0.1 (/playground)
error: unexpected closing delimiter: `)`
 --> src/main.rs:3:5
  |
1 | fn main() {}
  |        -- this block is empty, you might have not meant to close it
2 | 
3 | fn f) {}
  |     ^ unexpected closing delimiter

error: aborting due to previous error

error: could not compile `playground`.

To learn more, run the command again with --verbose.

Related: #68987. It looks like it will incorrectly point to last valid brackets of any kind.

The message changed, but it is still weird:

   Compiling playground v0.0.1 (/playground)
error: unexpected closing delimiter: `)`
 --> src/main.rs:3:5
  |
1 | fn main() {}
  |           -- ...matches this closing brace
  |           |
  |           this opening brace...
2 | 
3 | fn f) {}
  |     ^ unexpected closing delimiter

error: aborting due to previous error

error: could not compile `playground`.

To learn more, run the command again with --verbose.

Why should I care about those matching braces? Compiler might as well also tell me that 1+1=2.
