`<pedantic>` The regular expression that follows in the OP is `/./` in the split expression. And FWIW, it could, indeed, be a string literal: `c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le "my $tim = '01:00:01.004'; ;; $tim =~ s/:/./g; print qq{new time is '$tim'}; my @outputlist = split '\.', $tim; dd \@outputlist; " new time is '01.00.01.004' ["01", "00", "01", "004"]` [download] `</pedantic>` Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

If it was a string literal why do you need to escape the dot? I read thru `split` couldn't find a a mention of strings as separators. From my knowledge using a delimiter in single quotes is still a regex, albeit without variable interpolation like in double quotes. UPDATE After reading the dialog it seems that what you meant, a literal string without interpolation used as regex.

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.	[reply]

Well... I don't quite understand the point you're making, but... If it was a string literal why do you need to escape the dot? ... strings as separators. In my understanding, a string (or anything that's not a `Regexp` object) supplied as a `/PATTERN/` to split will be compiled to a regex, so a single- or double-quoted dot has meta-nature and must be meta-escaped to match only a period.
