## Profiling
```
stack bench --work-dir .stack-work-profile --profile --benchmark-arguments "compile lpgf testsuite/lpgf/phrasebook/PhrasebookFre.gf +RTS -T -p -h -RTS"
```
Produced files:
- `lpgf-bench.prof` - total time and memory allocation (`-p`)
- `lpgf-bench.hp` - heap profile (`-h`)
```
stack exec -- hp2ps -c lpgf-bench.hp && open lpgf-bench.ps
