This language is common in Indian English:

The more global way to say it is:
for quite a few years.

Please fix typo:

should be

Re:"Perl Regular Expressions are really tough" :
you could offer a link to https://regex101.com/ - a site that enables you to develop an debug (perl compatible) regex (PCRE).

I would simplify your "get_info" calling sequence and example to: 

#CALLING sequence
get_info ('first_name' => 'John',
           'last_name' => 'Doe'); 
#Implementation:
sub get_info {
    my %param = @_;
    die "ERROR: First-name is required" unless $param{first_name};
    die "ERROR: Last-name is required" unless $param{last_name};

   print "Your name is $param{first_name} $param{last_name}\n";
}

    Hi,

    Thank you for your valuable inputs. I've done the grammatical edits per your suggestion.

    However, I've kept the function same as before. That's because with a reference, even if I miss an argument in the calling function, it still executes. By using that, I wanted to show how Perl allows optional arguments.

      I don't understand what you mean by
      "even if I miss an argument in the calling function, it still executes"

      How is that behviour different than passing the hash (without a reference) ?
      Can you illustrate what you mean by an example?
