I like the second rule in perlref.
Anywhere you'd put an identifier (or chain of identifiers) as part of a variable or subroutine name, you can replace the identifier with a BLOCK returning a reference of the correct type.

Sure, the result is often ugly, but there are no exceptions or special cases. What more could my poor memory want.

    [ovedpo15]: it isn't homework. its a module I use at work. The process to add additional module isn't worth it. p.s never heard a university course which teach perl
    [marto]: there are many, to this day.
    [ovedpo15]: @Corion Yes I use the regex you showed me. its very good regex. although now i need to know that substring unit that comma
    marto mad corrections to one around 18 months ago
    [ovedpo15]: my code checks the value after that comma, if it isn't valid it will remove it. so I would like to remove the substring after that comma meaning getting the string before comma.
    [hippo]: Are you sure that Text::CSV_XS isn't already installed at your work? It's such a useful module that it might well be there.
    [marto]: pointing out the advantages of cpan modules is well worth in, as both developer and $client/$company benefit greatly
    [Tux]: $src =~ m{^(.*),(.*)$/ and $2 !~ $valid and $src = $1;
    [Tux]: s,/,},
