use Data::Dumper; %hash = (key => 1); local $hash{key} = 2; print Dumper(\%hash);# print 2 print $hash{key};# also print 2.
This clearly demos that $hash{key} is not another scalar, it simply refers to a hash element, which is a scalar. Again, please try to understand the subtle difference between "valid syntax to name an element of a collective, which happened to be a scalar", and "valid syntax for scalar name".

They will support it in Perl 5.10? Hope this will never happen ;-)

Let's look at from a different perspective. In c, you can say,
int a[200];
You can also say,
a[100] = 2;
but is a[100] a valid variable name? no, it is NOT. It can be used to call an array element, but it is not a valid variable name. It is the same situation here.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
