Now, after having played around with C# and .Net for awhile I have to say that standard support for emiting bytecode is great. I'm aware of thirdparty tools that can do this in Java such as ASM and BCel however I would really like to have a standardized way in Java for including inline "assembly". Having coded assembly quite a bit in my younger years I would like to have access to the power it gives me for certain code optimizations. Case in point is the sorting of primitive arrays or optimization of loops (for an example in C# see the Programming C# book).
