"No, because it's possible to implement efficient hash tables with C's primitives -- in fact that's how hash tables in essentially ALL languages ARE implemented."

Because each architecture has a C compiler that's been highly optimized. Popularity plus money invested. That's it. If you were right, we'd see optimizations coded in C even when alternative, optimizing compilers were available. I got a one-word counter to that interestingly enough from "high-performance computing" field: FORTRAN. Free Pascal people are doing fine in performance and low-level code as well despite little to no investment in them.

Seems throwing money at a turd (eg FORTRAN, C) can get a lot of people's hands on it despite some of us shuddering and saying "Get that pile of crap away from me!"
