I have some idea what I'm talking about, see my post https://news.ycombinator.com/item?id=25210523 and I don't kniow about why using a packrat over anything else. I pull something off the shelf, antlr for my latest project, then get on with it.

The parser is the most trivial side of things, if you consider that a key skill it comes across as being an issue from the 1970s, not today. Writing a RD by hand is not a big deal anyway as someone else said.

If your into optimising compilers you're focusing on a very odd area to criticise. I'd gave though more about dataflow using lattices or whatever, graph stuff etc.

So parsing aside, what are the 'relevant' skills you feel are missing?

(and what are 'Database Compilers'? Nearest I can think of that may fit are query optimisers)
