For the last few days, I've been looking for material about the Sapir-Whorf hypothesis (aka linguistic relativity) which states that people's thoughts are shaped by the language they speak. This is why, supposedly, Eskimos have fifty words for snow, the British have twenty words for rain and the Israelis have thirty words for taxes. I haven't found anything promising yet, but one hint did lead me to Paul Graham's book "Hackers and Painters".
The actual quote is "Our ideas about what's possible tend to be so limited by whatever language we think in that easier formulations of programs seem very surprising". This isn't exactly what I'm looking for. Elsewhere, Graham writes that the Prolog language "has fabulously powerful abstractions for solving about 2% of problems, and the rest of the time you're bending over backwards to misuse these abstractions to write de facto Pascal programs".
I feel the same about the programming language contained in Priority. I showed only a little of it in my previous blog, but I have known for a long time that certain operations - getting required data from a table or updating tables - are much easier to program in SQL than they would be in any other language, whereas supposedly basic operations such as looping and conditionals are on the level of assembly language.
