>they'll totally forget that allocation is expensive no matter what the platform or runtime.
Well, it's easier to do in a managed language. When you literally don't have to agonize or obsess over every allocation because you aren't responsible for cleaning it up (unmanaged held resources withstanding), you tend not to do so.
P.S.: You're always free to drop down into C or C++ if you want to get some speed, but of course you need to clean up after yourself there. A friend of mine wrote a good guide on doing so, if anyone cares https://github.com/TheBlackCentipede/PlatformInvocationIndep...
