Earlier quoted context omitted.
If Google can reuse names like "Go" and "Dart," then their "szl" is fair game for reuse.
Fair game sure, but unfortunately confusing. If there was another dart that was an actual programming language ( Is there ? ) you would have to qualify every time which dart programming language you meant. I imagine searching for things online would be tricky.
szl is the name of the compiler, not the language, but point taken.
