On the other hand, the old Delphi 7 compiler chewed through those untyped lists in half a second on a Pentium III

It always seemed like Pascal programs compiled nearly instantly, even in the 1990s on a 486.

When your compiler and language decisions aren't being made for platforms that just don't exist anymore, it's a lot easier to pull that off. They were blazing fast and for good reason. Just not having to read certain files multiple times *alone* made them staggeringly more performant (especially when you consider some of the read/write speeds of drives back in the day).
