in thread Matching dot using regexp

Somewhere in the middle of that doc it says that PATTERN can be
a string composed of a single space character (such as ' ' or "\x20" , but not e.g. / / ).
However, the only PATTERN strings that I find there are whitespace (PATTERN defaults to " " if omitted) and the empty string.

    split is happy with any string (or anything that can be converted to a string) as a /PATTERN/, e.g., 

    c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le
"my $tim = '10:00:10.004';
 ;;
 my @outputlist = split '[:.]', $tim;
 dd \@outputlist;
 ;;
 my $p = 10;
 @outputlist = split $p, $tim;
 dd \@outputlist;
"
[10, "00", 10, "004"]

["", ":00:", ".004"]

    However, I would incline to use  // qr// m// for any but the most simple and straightforward patterns; I vaguely recall pitfalls involving backslashes.

    Give a man a fish:  <%-{-{-{-<
