Static typed languages vs dynamic type languages is a much better separation but even then it is grey.
The pejorative "scripting language" was a term that Sun pushed really hard a while ago to separate them from "real" languages (i.e. Java) that you would trust your company to.
[Edit] I may have mis-remembered and it it might have been Oracle rather than Sun trying to dismiss "scripting languages" as toy languages at the time.
Fascinating. I do believe this without hesitation, but for the sake of sharing this in other social circles, is it the sort of claim that's possible to find a citation for?
I will keep looking. It may have been Oracle rather than Sun.
In it it basically talked about the need for constant low-level differentiation and playing-down of scripting languages.
The link you posted above is the kind of thing this encouraged. Don't be actively hostile but more "Oh, a scripting language? How cute"
"scripting language" used in a pejorative sense was pushed by Sun/Oracle.
