( #3333=superdoc: print w/replies, xml ) Need Help??

My solution in the root thread required was only minimally better than my original solution (to the wrong problem). This minimally tested version is vast improvement over both previous solutions.
#!/usr/bin/perl use strict; use warnings; my $end = shift || 22; my $next = lazy_merge( [ @ARGV ? @ARGV : (2, 3, 5) ] ); print $next->(), "\n" for 1 .. $end; sub lazy_merge { my ($list, $last) = (shift(), 0); my $by_n = sub { my ($n, $k) = (shift(), 0); return sub { $_[0] ? +$k += $n : $k } }; $_ = $by_n->( $_ ) for @$list; return sub { my $low; for ( @$list ) { my $val = $_->(); $val = $_->( 'next' ) if $val <= $last; $low = $val if ! defined $low || $val < $low; } return $last = $low; }; }

Cheers - L~R

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

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
