I totally agree, and said as much in What the [sub]in 'L value do they have?. I even suggested a few ways that the value could be made available to the sub without breaking existing code:
- By placing it into the scalar slot associated of the typeglob of the functions name.
- By placing it into $^_.
This is analogous to $^N as used in the (??{ code }) regex construct and is mnemonic* with $_.
Corrected per dragonchild's post below.
It could also be extended to @^_ for lvalue list assignment--which has interesting possibilities.
I think it probably would just require someone with the tuits to make such modifications to the sourcecode to produce the patch.
Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.

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).
