While many people have asked questions about how to teach Perl or where to learn it, an email today on the Perl Advocacy list mentioned a college professor that was not only teaching Perl, but was surprised by the overwhelming demand for it. You read about the course, if you're curious. In just browsing through it, I noticed a few things that were a bit odd, but all in all, it seemed far better than most material out there. Here's one of the questions from a quiz:
# Given:
sub pair {
my @out = ();
for (my $i=0; $i<@_; $i+=2) {
push(@out,[$_[$i],$_[$i+1]]);
}
return @out;
}
# What is the value of the expression
map { &{$_->[1]}($_->[2]) ? $_->[0] : () }
map { [$_->[0],$_->[1],'meowmoo'] }
&pair ( 'cat' => sub { $_[0] =~ /meow/ },
'dog' => sub { $_[0] =~ /arf/ },
'cow' => sub { $_[0] =~ /moo/ } )
# in an array context?
Reading through the course information is quite interesting. Enjoy!
Cheers,

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).
