That's exactly what Prechelt did. We need more of that.

Perl and Python ruled the roost in Prechelt's tests (from the POV
of development speed), indistinguishable from each other. C and C++
made the fastest executables on average. Java was bad on both
scores -- very slow programs taking a long time to develop. Other
scripting languages (Tcl, Rexx) gave intermediate development times
but extremely slow results. Somebody else claims to have rerun the
same experiment with Common Lisp, getting runtimes competitive with
C and C++ and development speed competitive with Perl and Python.
We could definitely do with more such tests...!!!
