The cycle detection in `nix repl`, `nix eval`, `builtins.trace`, and everywhere
|
|
else values are printed is now simpler and matches the cycle detection in
|
|
`nix-instantiate --eval` output.
|
|
|
|
Before:
|
|
|
|
```
|
|
nix eval --expr 'let self = { inherit self; }; in self'
|
|
{ self = { self = «repeated»; }; }
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
{ self = «repeated»; }
|
|
```
