It's never that simple. Python have some HUGE diference in terms of
semantics and runtime behavior for Java or .NET. People already
mentioned about the fact that it uses reference counting, this makes
object lifetime more predictable and all libs uses this fact.
Emulating this big semantic diferenc
Sven,
yep...am hoping Harmony folks would help with classpath too under
classpath terms and conditions of course.

Hi,
As a Classpath hacker (but by no means an important one)
here are my comments:

I agree with what you mean but don't like your wording. I may
personally love to help fix the occassional nit in classpath if its in
the way of harmony and will very cooperatively contribute it to
classpath. If I don't feel qualified to do it or thing others may be
better suited I'll kindly s

We can use the con call next week as the forum.
Folks,
Just to summarize *Ideally* what we would like, here's a list:
- We don't want to modify any classpath code. If we need changes, we
can work with classpath folks.
- We don't want to add classpath sources to our tree. this will avoid

I'm disinterested in the discussion of the value of other language

Why can a JIT not achieve 110% of native performance? (Assuming that we
strip out the compile time and compare like with like.)
The reason I say 110% is that binary code is usually compiled for the
lowest common denominator. So x86 code targets a 386, and Sparc binaries
target UltraSparc v8 or old

I think supporting other languages should be easy enough. Structs and
enumerations, for example, can be mapped to specific types of c

I'm talking about going directly from the language direct to byte-

Of course, if somebody wants to create the extra compilers, t

Isn't this the sort of thing Microsoft were trying to do with their
VM? Would we be in breach of the standard if we extended the
instruction set? Or were you thinking of some transient generation of
bytecodes at execution time? Kind of like "
