On: The Java type system is broken

[icedchai]

Good deal faster? I seriously doubt it. My understanding are generics are purely a compile time feature and does not effect run time.

I remember Java before generics: tons of casting from Object. The compiler is doing the same thing.

[mcculley → icedchai]

Those casts are still there. The compiler puts them in and the JVM has to execute them.

[icedchai → mcculley]

Yes. And my point is they'd be there anyway, with or without generics. It's not "generics" making the JVM any slower.

[mcculley → icedchai]

If the types were reified, the compiler and the JVM would know what type was there. No cast would be needed.

No. That's the point.
