    Thanks. Yes I have figured out how to workaround this limitation. It will be great if it is fixed some day.

[ovedpo15]: consider the following format of strings: some_data-doesn't- matter,value. how I get the value with regex? it should be after the last comma (last string)
[Corion]: Text::CSV_XS for all your CSV file parsing needs. Other than that, what problems do you have with perlre, and capturing everything after the comma? Also, index and substr would also work.
[choroba]: my ($value) = $string =~ /.*,(.*)/
[choroba]: The .* at the beginning matches the longest possible substring, so it eats any previous commas
[choroba]: But for CSV, use appropriate modules
