It's a fair assessment. I give more weight to designing a language 
around the way programmers are and the way they tend to work, rather 
than trying to force them adapt to the language.

As for the needs of programming managers, I think D is the only language 
that has attempted to address those needs. At least I've never ever 
heard of any other language even acknowledge the existence of such needs.
