And the reality is that languages are not compiled or interpreted, but there are implementation of language compilers or interpreters. The C language isn't "compiled", but there are some implementations of C compilers, and some implementations of C interpreters.

Another good example, is an old language, "BASIC", which a lot of people used the interpreted version, but, as early as 1987, I used a BASIC compiler which provided as much as a 100x increase in performance over the common interpreter that came with my system.

Python is another great example - lots of Python interpreters out there, but Cython lets you compile your python code to machine code.
