#[
This test illustrates some features of `debugutils` to debug the compiler.

## example
this shows how to enable compiler logging just for a section of user code,
without generating tons of unrelated log messages for code you're not interested
in debugging.

```sh
# enable some debugging code, e.g. the `when false:` block in `semExpr`
nim c -o:bin/nim_temp --stacktrace -d:debug -d:nimDebugUtils compiler/nim
bin/nim_temp c tests/compiler/tdebugutils.nim
```

(use --filenames:abs for abs files)
