lock as an lvalue sub that only locked for the duration of the current statement (not block) when used as an lvalue.
Hence
```
...
lock( $var )++;
..
[download]
```
would be a safe and concise substitute for
```
...
{ 
    lock( $var );
    $var++;
}
...
[download]
```
Also share( @array ) = ( some list ); would be nice.
And a share() that didn't wipe the var being shared, but rather operated recursively on its contents.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

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).
