Any language for which there exists an interpreter can also be compiled. Suppose there exists instruction X that is implemented in an interpreter by a finite sequence of machine instructions, {S}. X can therefore be compiled to {S}. There exists compilers for Smalltalk, Haskell, Scheme, etc.
Those are assembly emitting compilers for Smalltalk, Haskell, etc...? Do they implement the entire language? I was under the impression that smalltalk was interpretted. What about Lisp or ML?
And you can cheat it, like VB1/2/3/4/5 where they pack byte-code into the exe, and launch the interpretor from the exe. But I wouldn''t consider that native compilation.

Template meta-programming - the power of functional programming with the efficiency (and familiarity) of imperative programming.
I agree that any language to implement this would be most useful. The template functionality in C++ is just a way to infer a type from how the objects are used.

Type inference is something that functional languages have been doing for quite awhile. Throw in anonymous-classes or make functions first-class and I''d code in it in a heart beat.
