To implement it using your syntax you could do something like:
sub operate (&@) { my $sub = shift; local $~; $~ = &$sub($_) for @_; return $~ }

So for your examples you would get:
use strict; sub operate (&@) { my $sub = shift; local $~; $~ = &$sub($_) for @_; return $~ } my @list = (4, 6, 2, 67, 123, 645, 23, 54 ); my $max = operate { $~ > $_ ? $~ : $_ } @list; print $max, "\n"; my $string = operate { $~.$_ } @list; print $string, "\n"; open FILE, $0; my $count = operate { $~ + /operate/ } <FILE>; print "Count = $count\n";

And the results are
max = 645 string = 462671236452354 count = 4

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
