And why are they so small? (my perlbrew 5.38.2 is 3.4M) 
/usr/bin/perl		v5.30.3	169,856 bytes executable
/usr/bin/perl5.30	v5.30.3	134,608 bytes
/usr/bin/perl5.34	v5.34.0	134,608 bytes
There are 3 copies of everything in /usr/bin: 
perldoc			811 bytes executable
perldoc5.30		297 bytes
perldoc5.34		297 bytes
Core modules for each version: 
/System/Library/Perl/5.30
/System/Library/Perl/5.34
Older versions of macos had two copies of everything in /usr/bin but they were the same version of perl. This is on macOS Sonoma 14.3 version 23D2057. The question arises from Re^2: object version does not match.
