This is going a long way away from sci.lang, but would you be so kind as to indicate what optimizations you have in mind that don't apply to C (never mind C++). Isn't optimization carried out using intermediate languages more primitive than C? > > Your "easy to write a compiler for" is more to the point.

Wouldn't that imply that writing a better compiler was an interesting business opportunity? Writing a dumb compiler is easy (and tedious). All the skill is in the optimization.

If being called by some name doesn't make an entity an example of the things called by that name, then what does?
