I walked into this one by catching mention of '~~' and of a count of how many modules might contain it as the discussion was ending for a while in the CB, and was unable to come up with the numbers before it ended. Here, however, are my numbers and methods, in hopes they may be of help.
- Version of perl: 5.8.3, installed on Mandrake 10.0 from RPM.
- Command used to generate listing: perl -MCPAN -e 'autobundle;'
- Number of modules installed (perl -ne 'print if (m/CONTENTS/..m/CONFIGURATION/ and not m/^\s+/ and not m/^=/);' ~/.cpan/Bundle/Snapshot_2005_03_14_00.pm | wc -l): 3_566
- Number of files under /usr/lib/perl5 (find /usr/lib/perl5 -type f | wc -l): 8_982
- Number of lines in files under /usr/lib/perl5 (find /usr/lib/perl5 -type f -exec cat "{}" \; | wc -l): 3_298_000
- Number of files containing '~~' (find /usr/lib/perl5 -type f -exec grep -il '~~' "{}" \; | wc -l): 93
- Number of lines containing '~~' (find /usr/lib/perl5 -type f -exec grep -i '~~' "{}" \; | wc -l): 170
- Number of files containing '~~', by type (find /usr/lib/perl5/ -type f -exec grep -il '~~' "{}" \; | xargs file | gawk '{FS=":"; print $2;}' | perl -pe 's/^\s+//;' | sort | uniq -c | sort -n):

In looking through those files (minus those ending in '.so'), all cases I could find of '~~' appeared either in format statements, as delimiters, or in comments.
I do not know if this information is of use, but I hope it will prove helpful. (The list of modules and versions is below.)
Update: 14 Mar 2005
The listing was too long; therefore, the remainder of the list will be appended as a response to this node.

Thank you very much for doing this research. This saves me some work (downloading a mini CPAN finished only an hour ago).
And thanks for splitting it, because now I can ++ you twice! :)

hum, I've downloaded a few of those modules, but I haven't yet found any '~~' in any of them:
xmath@quoose cpan/build$ ls
Algorithm-Annotate-0.10 Algorithm-Evolutionary-0.53
Algorithm-BinPack-0.4 Algorithm-Evolve-0.03
Algorithm-Bucketizer-0.10 Algorithm-FastPermute-0.07
Algorithm-CheckDigits-0.38 Algorithm-FloodControl-1.00
Algorithm-ChooseSubsets-0.01 Algorithm-GDiffDelta-0.01
Algorithm-Cluster-1.28 Algorithm-GenerateSequence-0.02
Algorithm-Diff-1.1901 TransitiveClosure-1.4
Algorithm-Diff-Apply-0.2.3
xmath@quoose cpan/build$ grep -rs '~~' *
xmath@quoose cpan/build$
Am I missing something, or did you do something wrong with the search?
addendum: oh, this is a list of all modules checked? If so, I misunderstood. (a list of modules where you found ~~ would have been more useful to save downloading those which don't :-) | [reply]
