- @_=/./g;: The RHS of a list assignment operator is evaluated in list context.
- ()=/./g;: The RHS of a list assignment operator is evaluated in list context.
- /./g;: A expression statement followed by another statement is evaluated in void context[1].
- (/./g);: A expression statement followed by another statement is evaluated in void context[1].
- ()==/./g;: The RHS of a comparison operator is evaluated in scalar context. [Updated]
- $_[/./g];: The index expression of an array element is evaluated in scalar context.
- /./g;: The statement at the end of a while loop is evaluated in void context.
The behaviour of the match operator in void context doesn't appear to be documented, but is sensibly acts as if it was evaluated in scalar context.
$ perl -E'$_="abc"; /./g; /(.)/g; say $1'
b
- Not scalar context, as previously mentioned.

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).

or How to display code and escape characters
are good places to start.
