Easy way to print Perl array? (with a little formatting)

Question

Is there an easy way to print out a Perl array with commas in between each element?

Writing a for loop to do it is pretty easy but not quite elegant....

Answer 1

For inspection/debugging check the Data::Printer module. It is meant to do one thing and one thing only:

display Perl variables and objects on screen, properly formatted (to be inspected by a human)

Example usage:

use Data::Printer;  
p @array;  # no need to pass references

The code above might output something like this (with colors!):

   [
       [0] "a",
       [1] "b",
       [2] undef,
       [3] "c",
   ]
