What a clever inefficiency! I was trying to find a way
to generate a list of numbers that was at least as big as
each list, but failed...
With ?: I can save some, and shaving with map$foo,@list
tricks I can save some more. This brings the safe version
down to 48 characters.
sub Mix {
map{my$i=$_;map$i<@$_?$$_[$i]:(),@_}0..map@$_,@_
}
That matches what was done unsafely before. But
unfortunately for sanity's sake observe the following
33 character entry:
sub Mix {
map{splice@$_,0,1}map@_,map@$_,@_
}
I have written saner code...
UPDATE
Saved 3 chars on the unsafe example, there is no need
for a nice numerical list when I will be just converting
the elements...
UPDATE 2
Sheesh. And the safe example can be modified to the
rather bizarre 45 character beast:
sub Mix {
map{splice@$_,0,1}map@_,map@$_,@_=map[@$_],@_
}
UPDATE 3
I give up on shrinking this. However I have 4 variations
on the key 33 char sub. In terms of efficiency of
execution, the following wins:
sub Mix {
map{map{splice@$_,0,1}(@_)x@$_}@_
}
So that is (barring the unexpected) my final answer.

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).
