I thought about that one too, but it also follows @ISA. You can fix that with this:

do { local @ISA; __PACKAGE__->can("do_$type") }->();

Much smoke. Many mirrors. In fact, I'd cache the result too:

BEGIN {
  my %cache;
  sub do_it {
    my $func = shift;
    ($cache{$func} ||= do { local @ISA; __PACKAGE__->can("do_$fun") })
      ->(@_);
  }
}
...
do_it("function", $arg1, $arg2, @more_args);

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or or How to display code and escape characters are good places to start.
