Agreed completely. I'm doing a decent amount of development with MCUs these days and really like having a minimal abstraction. It's easier to think about what the hardware is doing when you're only slightly removed from the assembly; what would be a convenient abstraction for most application development quickly becomes a liability as knowing the implementation details can be pretty important (due to limited resources).
As for an implicit "this" for function pointers, I've had the same wish myself. I've settled for just a function namespace (ie: myListPush(myList,foo);) due to the verbosity of your example but it's not quite the same. At this point I'm pretty happy without it, and even think it might be hiding too much information, but it makes a nice piece of syntactic sugar for sure. My current unneeded-but-desired change to C would be the addition of lambdas like in C++11.
