I actually think that's pretty cool, despite my desire to see a native switch. I have often use hash constructs to accomplish switch-like behavior, and I think that the for ( $var ) ... approach is much nicer...
# Example of the hash-construct "switch", which is limited and has no
+"default".
# The output of this code is "abc"
use Moo;
my $val = 'c';
my @args = qw( abc );
my $obj = __PACKAGE__->new();
{ a => sub { say 'a' },
b => \&b,
c => sub { $obj->c( @_ ) },
}->{ $val }->( @args );
sub b { say 'b' };
sub c { shift; say for @_ };

A mistake can be valuable or costly, depending on how faithfully you pursue correction

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).
