[Qbs] How do I use Parameter property in a module itself?

[Иван Комиссаров]

However, this is an interesting question.
Is it true that all module properties should be allowed to be set per-file?

 Product {
      Depends { name: "mymodule"; }
      mymodule.useFeature: true // enable some probes here, do heavy checks

      Group { files: «file»;  mymodule.useFeature: false; } // does nothing, all checks are already done
  }

What worse, this won’t work at all:

 Product {
      Depends { name: "mymodule"; }
      Group { files: «file»;  mymodule.useFeature: true; } // ooops
  }
