Hmmm.....
Even I am a beginer but let me throw some pointers. Experienced users kindly
correct me if I am wrong....
First line is declaring a constant. What I could not get is that what
constant are we trying to declare i.e a variable, hash or a reference.
Read more - perldoc constant
And then there is a function which perhaps is returning a reference to
something.
Sorry for this vague kind of answer but even I am in process of learning
Perl. :)
Cheers,
Parag
