Note that `break` and `continue` can only be used inside a `for` loop.
V does not have a way to forcibly "unwrap" an optional (as other languages do,
for instance Rust's `unwrap()` or Swift's `!`). To do this, use `or { panic(err.msg) }` instead.

Another example, is if you want to embed the version/name from v.mod *inside* your executable:
```v ignore
import v.vmod
vm := vmod.decode( @VMOD_FILE ) or { panic(err.msg) }
vm := vmod.decode( @VMOD_FILE ) or { panic(err) }
eprintln('$vm.name $vm.version\n $vm.description')
