Often Ada is not used for the very low-level stuff, that directly interfaces with the hardware.

Which is sad, if true, because Ada has better support for low-level hardware interface than most other programming languages, in chapter 13 on representation specifications, which allow specifying precise bit-level definitions of data structures (e.g., hardware registers). Admittedly it's an optional feature, but C doesn't have anything similar, since the ordering of C bitfields was deliberately left undefined.

I was an Ada programmer for a few years, using the original Ada 83. I liked it fairly well other than not having function pointers. Function pointers and object oriented facilities were added in Ada 95.
