So, effectively Ada and Rust.  Which effectively means Rust.<p>I was really hoping that the list would be longer than that.  :(<p>&gt; Ada<p>&gt; Spark<p>&gt; Rust<p>Ada (Spark is effectively Ada) and Rust<p>&gt; D<p>Nope.  Garbage collected doesn&#x27;t work for systems programming.<p>&gt; Swift<p>Not sure I buy this.  When I see someone chewing on an OS in Swift I might believe it.<p>&gt; FreePascal<p>&gt; Delphi<p>Dunno about FreePascal, but my anecdotal experiences with Delphi programs have left me wishing that their authors had written them in C.  It is, of course, possible that the programming teams were bad, but it sure seems like Delphi isn&#x27;t any better than C in that respect.
