Nonetheless, in an (my) ideal world you would be able to derive the long form from the abbreviated form by:
1. knowing the outlines of your territory (files, dirs, packages, systems, context of all kinds)
2. looking at and hopefully understanding the "mechanics" of the code
Admittedly that isn't cheap, although it seems doable for an outsider. (eventually we are all outsiders)
All in the name of circumventing names that are hard to understand. (for outsiders)
The more I think about it I come to the conclusion that excessive use of long names are a way of "getting more intimate"
with your code. That helps you personally (or a small group) over the short-, midterm (maybe even long-term or
the rest of your life) but harms others.
In the end, it seems to me, it all comes down to not having any standards and a practically infinite number
of possible meanings. (costs of sharing meaning, transaction costs)

That makes sense to me.
Sounds like you are making a case for using long names as an asset by having the contrast between long and short.
And the costs of sharing meaning about a name that gets used frequently are easier to justify.
Again, opens the question as to how much long names are capable of reducing costs of sharing meaning.
Could they even increase the costs? I certainly made that case. Seems a little crazy from this perspective.
Surely the more words you use to describe something the easier it gets to share what it actually means?
Does purpose come into play now? Maybe I should stop here.

Right, only context is missing in this picture.
Hm, the costs of sharing meaning often seem to be exceptionally low when it comes to context.

Impressive, a testimony from the New York Times. Yes, this is awfully off topic.
As a side note: The relative low level interface of hu.dwim.rdbms I was talking about,
on top of which as many extensions as possible can be build, seems to be already there.
It's just that it isn't properly exposed, in my eyes at least.
>writing code has much more utility than talking about writing code...
Hard to tell. On average you are probably right.

I take this as an compliment. (normally I refuse compliments, tells me something)
