The olden days are not that old. I find myself using static arrays, free lists, malloc and its OO brethren as well as GC when available. All of those things have been around for as long as I can remember. It's nice not to have to worry about freeing allocated memory but if you write a lot of low-level code there's a certain level of unease about letting the language or OS take on something that can have such a large performance impact.
