SPUG: hashes, arrays, map, join

[John Cokos]

To summarize .....

It seems that these are the options presented by you all:

Alternatives to the use of map in populating the has to start with:
    %ids = split /[,:]/, $results;
    %ids = $results =~ /(?:^|,)(\d+):(\d+)(?=,|$)/g;

To recreate the hash afterwards:
    These appear the same, but just for grins, I'll try them separately.
    join (',', map {"$_:$ids{$_}"} keys %ids);
    join ',', map "$_:$ids{$_}", keys %ids;

    ** Thanks for these ... this was the focus of my mental block to day
        Looking at it here, I can't believe I didn't "get it" earlier, I
tried,literally
        every combination of things but THIS one **


Anyway, I'm loading the DMOZ Data right now, into mySQL, so I'll have
a good 30 to 40 million indexed words to monkey with.  I'll report back
some time trials on each of these methods.

John
