[perl #105922] Allow any string before ->meth
The rules for filtering out what do not look like package names are
not logical and disallow valid things like "::main", while allowing
q"_#@*$!@*^(".
This commit simply lets any non-empty string be used as a package
name. If it is a typo, you’ll get an error anyway. This allows
autobox-style calls like "3foo"->CORE::uc, or even "3foo"->uc if you
set up @ISA first.
I made an exception for the empty string because it messes up caches
somehow and causes subsequent method calls all to be called on the
main package. I haven’t looked into that yet. I don’t know whether
it’s worth it.
The changes to the tests in cpan/Test-Simple have been submit-
ted upstream.
Mentioned in perl5180delta:
Class method calls are now allowed on any string, and not just strings beginning with an alphanumeric character. [perl #105922]

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).
