I was afraid that mentioning that would cause confusion. Exupery is a
JIT written in Smalltalk, the compiler runs as a normal Smalltalk
process in the image just like any other Smalltalk code. It needs a VM
with a few hooks to allow the native code it generates to be executed.
The VMs I provide have both those hooks and the closure bytecodes.
Support for both Exupery and closures is in the VMs.
Exupery itself is a normal Monticello package which is available via
SqueakSource or Universes, if you haven't loaded it and started it then
there is no risk.
