This is meant as an argument in favor for functional programming.
I think that moving away from an imperative statement-oriented style towards a declarative expression-oriented style does indeed help us not to fall into the vicious write-debug-circle. I mean, do you debug your SQL-expressions?
On the other hand, isn't the possibility to assemble a complex program from simplest instructions the strength of imperative languages? Is it only my brain that has repeatedly problems to wrap itself around ever growing, conceptionally twisted SQL-expressions? I thought it was a common agreement, that SQL is hard to maintain? I would put a big part of the blame on its declarative style, that does hardly allow decomposition or modularization... and I am a bit afraid of seeing mainstream application languages moving in this direction.
And somewhere out there is still lurking the danger of ready-only languages.
