This is an easy answer which can be found on the homepage of both the Perl11.org and RPerl.org websites. But sure, I can re-explain it for those who didn't bother to read the basic source material! ... RPerl compiles Perl 5 into C++, which can then be further compiled into a binary or shared object or bytecode or whatever you like with your own favorite C++ compiler. Yes, you can consider RPerl to be a "transpiler" if you like the term. The resulting C++ code has virtually no runtime overhead, and thus runs at least at the speed of native C++. RPerl also offers automatic parallelization via integration with the PLUTO polycc compiler collection, which can often provide faster-than-normal-C++ performance.
