Hmm, looks interesting, but it's quite unfortunate that making the compilation process be useful at runtime-error-removal is merely optional ("strong mode"). So one wonders how many shops write enough "prototype" code in "weak mode" that they decide to leave it in its Python-like mess instead of rewriting for "strong mode"...

Don't worry; strong mode will be the only mode going forward and it already is the only mode for Flutter. Not merely optional.
