would this dispatcher like syntax be OK for you?
till (
- /match0/ => \&doOtherProcessing,
- /match1/ => \&doStage1,
- /match2/ => \&doStage2,
- /match3/ => \&doStage3,
)
of course you are also free to write something like
till (
- /match0/ => sub { print "default Processing" },
- yadda yadda ...
)
please note that the minus is obligatory to:
- enforce scalar context around the /match/
- avoid "empty" values which are ignored in lists³
Furthermore you'll need to bind the state¹ of
till() to it's position, i.e. using
caller to determine filename and line number of invocation.

¹) e.g. the $fn here
²) Consequently you shouldn't use two till()'s within the same line, otherwise they'll share the same state.
³) minus transforms true => -1 , false => 0

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).
