Paint me daft, then, I do it all the time in tests. :)
Perhaps any extra arguments to can() could be bound to the subref returned. It's a nice idea; it just seems really hard to get super-scary magic right. Here's some untested code that seems somewhat useful:
use Scalar::Util 'blessed';
sub curried_can
{
my ($thingie, $func) = splice( @_, 0, 2 );
my $sub = UNIVERSAL::can( $thingie, $func );
# $thingie cannot $func
return unless $sub;
# first argument is an object
return sub { $thingie->$func( @_ ) } if blessed $thingie;
# first argument is a class name, no arguments
return $sub unless @_;
# first argument is a class name, curried arguments
return sub { $sub->( @_ ) };
}

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).
