Yes. But the speed is dependent on whether or not the compiler makes use of that information and the machine architecture the compiler is running it on.

Speed is a function of all three -- not just the language.

Optimizations for one architecture can lead to perverse behaviours on another (think cache misses and memory layout -- even PROGRAM layout can affect speed).

These things are out of scope of the language and as engineers I think we ought to aim to be a bit more precise. At a coarse level I can understand and even would agree with something like "Python is slower than C", but the same argument applies there as well.

But at some point objectivity ought to enter the playing field.
