They're different operators. => is the same thing as the comma. It's sole
difference is readability. For example
%hash = ( key => "value",
key2 => "value2",
);
#is the same as
%hash = ( key, "value",
key2,"value2",
);
#is the same as
%hash = ( key, "value" =>
key2,"value2" =>
);
#Although that last one is confusing...
-> is an operator useful when dealing with reference. Not to get into too
much detail, because it sounds like you're pretty new at Perl from your
questions, if
$hash_ref = {key => "value", key2 => "value2"};
print $hash_ref->{key};
It will go and get the 'key' key from the hash that $hash_ref points to. This
works for array, packages, and other stuff too. For example, Foo::Bar->new
means to go into Foo::Bar module and do the new subroutine.
