I am more of the side that invoke dynamic is awesome for enabling dynamic
languages on the
JVM. Given that there are two areas where I can see some help for my use
case which
is a true Smalltalk on the JVM.
First like Charles I do have a few dependencies on plain old Java methods
during startu
In answer to Charles question on what others do to help the startup.
Smalltalk is like Ruby in that we always start from source code. In our
case
there are a few hundred classes and a few thousand methods that would
be considered minimal ( we call these the base ) and around a thousand
classes a

Like Clojure, I'd only consider Kawa to be *somewhat* dynamic. Most

Forcing all handles to compiler early has the same negative

2. Lambda forms are too slow to execute and take too long to optimize
down to native code. Lambda forms work sorta like the tiered compiler.
They'll be interpreted for a while, then they'll become JVM bytecode
for a while, which interprets

Hi Per!
This is mostly invokedynamic related. Basically, an indy callsite requires a
lot of implicit class and byte code generation, that is the source of the
overhead we are mostly discussing. While tiered compilation adds non
determinism, it is usually (IMHO) bearable…
