I have seen interpreters for both C and Pascal. It's probably easier to write an interpreter for those languages than it would be to write a compiler for Perl given Perl's eval that pretty much requires an interpreter or some sort of runtime just in time compilation.

I guess part of the distinction between a scripting and other languages may be the degree of typing and type safety provided by the language with scripting languges generally being less fussy about such things and non-scripting languages being more fussy. At the end of the day "scripting language" is a pretty meaningless label.
