I am not entirely sure I get your point. You mean that if you mistype the comma in
@array[10, 42]
(which would be just two elements of @array similar to Perl5) and accidentally change it to a semicolon
@array[10; 42]
then you get a multi-dimensional array? Do arrays automatically promote to multiple dimensions? If this is the case, then it is indeed a call for stupid mistakes, which are hard to uncover...
By the way: for me at least Perl 6 native multi-dimensional arrays do not seem to be essential. I mean they are pretty nice, but I could definitely live without them in Perl 6.0.0. At least, poor autrijus might have some less sleepless nights implementing hard-to-implement-only-marginally-useful language features...:-)

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.
