On: The Generic Dilemma in Go

[derefr]

What's wrong with using both approaches: debug binaries get compiled with boxing generics, while release compiles using macros?

[extempore → derefr]

Scala offers both (not in a release version yet, but not far off) by way of @specialize. http://www.scala-lang.org/sid/9

[stcredzero → derefr]

Or have the former as the default, and allow the programmer to opt for the second, if the optimization is needed?

[gfodor → derefr]

Cool idea. Has this been done in any language before?
