In the development distributions, always available at http://git.savannah.gnu.org/cgit/bash.git/snapshot/bash-devel.tar.gz Or you could just clone the git tree. > > However, I have made some tests.

Running this code > (from https://unix.stackexchange.com/q/462084/265604): I'm going to assume you're running the pre-release distributions on a Linux system where the debugging code in the bash malloc is enabled. When I try timing the entire script on bash-5.0.2 (Mac OS X), adding `time' calls before `f2 "$@"' and `main', I get args = 1 1 function no args yes real: 0.006 2 function yes args yes real: 0.012 3 function yes args no real: 0.012 args = 20000 1 function no args yes real: 0.006 2 function yes args yes real: 0.012 3 function yes args no real: 0.013 real: 0.078 real: 0.503 real 0m0.529s user 0m0.464s sys 0m0.104s which is comparable to ksh93, which produces real 0m0.459s user 0m0.349s sys 0m0.107s for the entire script. So I'm comfortable saying there's no big performance issue here.
