Then how do you write the bridge method?  You'd have to apt it into  
the class file.  And then you'd need another mangling convention to  
relate the Java name to the actual name.

It's simpler to make these things direct.  Since the JVM supports  
such names, and since Java is the system programming language for the  
JVM (isn't it?), let Java support those names.

But it's a separable part.  And I think the trend with JSR 292 is to  
make dynlang call sites look more like Java call sites, reducing the  
amount of adaptation required.

This does raise the question of how to emit the extended call  
bytecodes from javac (if at all).  Not an easy question, but a simple  
low-level solution would be worthwhile.
