Maybe I'm not smart enough for Smart Match ;)
It seems that the operands in Smart Match are swapped to what I expected after reading the docs
Is perlsyn#Switch statements clear???
Most of the power comes from implicit smart matching:
when($foo)
is exactly equivalent to
when($_ ~~ $foo)
($_ was given)
and
# $a $b Type of Match Implied Matching Code
# ====== ===== ===================== =============
...
# Array Regex array grep grep /$b/, @$a
see perlsyn# Smart matching in detail
so when writing
given (@a) {
when (/abc/) {}
}
I expect this to be tested:
@a ~~ /$b/
in the meaning of
grep /$b/, @$a
Two possibilities:
a) the docs need a rewrite!
b) my brain needs a rewrite! ;)
Cheers Rolf ...still confused...
UPDATE: Sorry personally I think that ~~ is far too overloaden with functionality to be easily understood!!!

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).

are good places to start.
