C has lot of reference materials and Books to explore the hidden treasures. Does PERL has any books/Reference to explore its hidden treasures.

It has excellent documentation in addition to many books.

I am looking something like, 
$a = 10; $b = 20; print $a +$b;

[download]

perldoc -f print.

This code will not print 30 as there is ambiguity in the print statement. It treats $a as file handle and + before the $b as prefix operator and tries to print $b to $a.

There is no ambiguity, although one has to admit that the case may be confusing. But it's perfectly well documented.

Is there any place where these kind of hidden treasures are listed ?

Again, in the docs, in which as a perl_lover you will also be delighted to discover that it's also explained why there's not such a thing as PERL: see perldoc -q difference between "perl" and "Perl".
