pvfki has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am relatively novice to Perl and had installed Math::Prime::Util::GMP modules. I am trying to adjust some of the subroutines in Math::Prime::Util by finding the .pl files for each of them in the directory libraries. For instance, I want to add / change the parameters to sieve_range() function by simply finding a .pl file for the subroutine and changing the code inside the file. Unfortunately, I did not find any such file. The closest thing I found was a file called 'sieve.c'. Is there still a simple way to change the subroutine's parameters and variable meanings manually or is the subroutine hard-coded (not easily to manipulate)?
