You could win a little time by not copying your data twice : @{$ref}{@head} = split(/\t/); (which will even make split a little faster if you put the result in less elements than there are tab separated values in your string).

Or you could keep the array, and access its elements with constants, like was done here for example (it's done on a blessed arrayref in this case, but it works all the same).

    [TCLion]: at least that's the plan
    [1nickt]: Corion this looks good, from the pod: "there are 9000+ variations that are detected correctly in the test files (see t/data/* for most of them). If you can think of any that I do not cover, please let me know."
    [TCLion]: some moron put the date like this : Mon Feb 20 09:31:30 2017
    [Corion]: 1nickt: Yes, the module sounds promising indeed
    [1nickt]: "putting the date in correct order" how?
    [Corion]: TCLion: Whee ;)
    [TCLion]: need to put like this : 2017-02-20 09:30:53
    [1nickt]: That's why I asked if you are using DateTime. It has a large number of supporting modules (the author likes the term 'eco-system') so if you are already creating a DateTime obj from your dates, this module would read in the mnoron-formatted 1s seamlessly
    [TCLion]: when I put the date together it looks like : 2017-Feb-24 (month is the problem)
    [1nickt]: good luck, then.
