I think it would help if there was some way to prepare functions to
allow them to be posted and understood more easily. These would help:

* a name obfuscator, so people can post functions without revealing
inner workings of their company and potentially lose intellectual
property rights over code posted in that way

* a pretty printer, so we can better understand them when we see 'em

Without these, I think we need to realise that many people will never
post their SQL at all.
