The remark wasn't directed specifically at you.  Having disparaged
perl weenies favorite solution to everything, I was just a little
surprised that they hadn't jumped all over it already. ;-)

Oh, I know there _is_ a perl solution, I used to write them.  The
technique I used to use was to read file1 into a hash table and then
loop through file2 comparing the appropriate fields in each line
against presence in the hash table.  This solution lacked
"onelinedness".  I presume there are other, perhaps better, perly
ways.  My question (challenge) was an invitation to hear about them.
