Squeak (a smalltalk dialect) has its kernel written in a subset of squeak which can be either interpreted or compiled into assembler. The former maintains the development/testing advantages of an interpreter and the latter makes it run at a decent speed. You may be able to do the same with Python. Alternatively, JIT techniques have received an enormous amount of effort over the past decade (thanks to Java) and a JIT Python may be reasonable. > Oliver (right now busy writing a boot manager in assembler) Not Python?? :-) -- Peter Jeremy
