Cycle error when accidentally comparing a function inside itself #66667
Description
The following code leads to an inscrutable error message:
fn up() {
up == 1
}error[E0391]: cycle detected when processing `up`
--> src/lib.rs:1:1
|
1 | fn up() {
| ^^^^^^^
|
= note: ...which again requires processing `up`, completing the cycle
= note: cycle used when type-checking all item bodies
error: aborting due to previous error
I had this happen in a 10-line function and it took me a bit to realize that I typo'd the function instead of a variable name somewhere. There is no indication where inside the function the bad use is.
