Came across this http://dn.codegear.com/article/38715 today and found that CodeGear has finally fixed all the compiler bugs I've filed in 2005 (3 years ago). Heck, if you do a search for "Zach Saw", you'll find that one of the entries has a path to my "My Documents" ;)
Anyway, kudos to Embarcadero to let the team work on these C++ compiler bugs which turned most of us away to the clutches of Microsoft Visual Studio / C# back then. These compiler bugs were by no means trivial - they were so nasty that they simply rendered any effort to create a stable 24/7 server impossible.
With all these bugs fixed, C++ Builder would now be the definitive tool to create a proper server (especially versus C#) - low memory usage, blistering fast and it shares most of its the design patterns with .NET (in fact, one would argue that C# is heavily inspired by Delphi / C++ Builder). I spent just 3 days writing a framework which is intimately similar to .NET's asynchronous IO design and its Control.BeginInvoke / Control.Invoke design. In case of the latter, I found that with C++, you get more type checking than you would with C# in passing parameters to the callback. In fact, even the return type for EndInvoke could be type checked with RTTI (during run-time unfortunately, but in any case, is automatic unlike .NET).
