Description Tim Chevalier 2022-08-18 17:18:09 PDT 
I found the following error message to be confusing:

```
[📦🌐🐱 org.webkit.Sdk GTK@Debug WebKit]$ WebKitBuild/GTK/Debug/bin/jsc  -m JSTests/wasm/gc/arrays.js --useWebAssemblyGC
ERROR: invalid option: --useWebAssemblyGC
```

Eventually I figured out that the flag needs to be `--useWebAssemblyGC=true`. It would be nice if, in general, rather than just "invalid option", the error message included a hint about what the argument for the flag should be.
