Why doesn't Perl support interpolation of hashes in double quotes?

Question

#!/usr/bin/perl
use warnings;

my %hash=(\"no1\"=>1, 
        \"no2\"=>2,
      );

print %hash; #Prints no11no22
print \"%hash\"; #Prints %hash

Answer 1

To quote Nathan Torkington: "The big problem is that % is heavily used in double-quoted strings with printf." More information is here.
