Thank you very much Sam and Wade for the response. strict refs mode is fine. But I just wanted to know if I understood right! When you use the -> operator the '$' sigil is not necessary! Perl automatically understands the type i.e whether array or hash.

I personally believe you're right. More precisely, with the symrefs thingy others duly explained to you, the -> dereferentiation operator, complete of the correct parens -AFAICS it doesn't exist by itself- is unambiguous enough for the correct slot to be selected. However you should not use symrefs, anyway. (But under particular circumstances.) Rather, I feel like pointing out that main->{x} = 1; is still valid syntax, under strictures, although it has to be associated with a different semantics than yours:

$ perl -Mstrict -wle '
> my %x; sub main () { \%x };
> main->{x} = 1;
> print $x{x}'
1
