Sorry, I really meant underscore. Anyway, tilda is indeed discussed
as a possible concatenation operator.
It makes indeed sense to use the same sign for the unary
conversion to string and the binary concatenation. Also
the underscore was less than ideal because it is used for
identifiers. So that meant that it had to be surrounded by
space.
There are very long threads in p6l about operators in general
and concatenation in particular. Indeed, the status of
underscore as concatenation character is contested and
tilda seems the main contendant but that does not
seem a done thing.

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).
