I found this gem of a snippet today, and I rather agree with what it says!
\n\n\n“How solemn and beautiful is the thought that the earliest pioneer of civilization, the van-leader of civilization, is never the steamboat, never the railroad, never the newspaper, never the Sabbath-school, never the missionary — but always whiskey! Such is the case. Look history over; you will see.
\nThe missionary comes after the whiskey — I mean he arrives after the whiskey has arrived; next comes the poor immigrant, with ax and hoe and rifle; next, the trader; next, the miscellaneous rush; next, the gambler, the desperado, the highwayman, and all their kindred in sin of both sexes; and next, the smart chap who has bought up an old grant that covers all the land; this brings the lawyer tribe; the vigilance committee brings the undertaker. All these interests bring the newspaper; the newspaper starts up politics and a railroad; all hands turn to and build a church and a jail — and behold! civilization is established forever in the land.
\nBut whiskey, you see, was the van-leader in this beneficent work. It always is. It was like a foreigner — and excusable in a foreigner — to be ignorant of this great truth, and wander off into astronomy to borrow a symbol. But if he had been conversant with the facts, he would have said: Westward the Jug of Empire takes its way. ”

\nLets assume I have a complex record that contains a number of \"sub\" records that need to be modified during a program's execution time. One scenario this could happen in is a record called \"Table\", that contains a \"Row\" which is updated (Think database tables and rows). Now this can be implemented in two ways,
\n \n{:filename "tab1name",\n :tuples\n #<ref :field="" :tupdesc="" nil="">},\n :tup #<ref :name="">}\n {:recordid nil,\n :tupdesc\n {:x\n #<ref :field="">},\n :tup #<ref :name="">}}>,\n :tupledesc\n {:x\n #<ref :field="">}}\n\n\t</ref></ref></ref></ref></ref>\n \n#<ref :field="" :name="" :tup="" :tupdesc="" :tupledesc="" :tuples="" nil="">\n\n<p>\nSo at this point, which method would you recommend?</p>\n<p></p>\n</ref>\n --

However, my objective is slightly more intricate – I’d like to serialize records that are actually refs. I see a few options for this,
\n– Either use a method that puts a record into a ref, rather than a ref into a record and then use the serializable, top level map
\n– Write my own serializer to print this to a file using clojure+read
\n– Use Java serialization functions directly.
Thoughts?
