I'm not the only one using semi-colons. I think I picked this up from Larry Rossler (the one from the GRT) back in the 1990s.
But your use of parenthesis still makes it ambiguous. Perl may now guess right, but it's still a guess. {("x$_" => 1)} can still be a hashref. Perl will guess incorrectly if it's written as:
my @y = map { ("x$_" => 1) }, qw(a b c);
But feel free to do whatever works for you. Don't do something just because others do it, or not do something because others don't.

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.
