Nicolas Cellier uploaded a new version of FFI-Kernel to project FFI:
http://source.squeak.org/FFI/FFI-Kernel-nice.118.mcz
==================== Summary ====================
Name: FFI-Kernel-nice.118
Author: nice
Time: 21 June 2020, 1:20:34.369348 pm
UUID: a8c48997-991d-4e32-9b67-6d93fc0dabe0
Ancestors: FFI-Kernel-mt.117
Add the ability to allocate: an ExternalType or an ExternalStructure/Alias.
It's equivalent to new: but we want a specific idiom, C types are not exactly classes.
Add the ability to compare aliases (at least for equality)
