v0.1.6 Yodeling Yellowjacket

Large learnable parameter re-factor - learnable parameters can now supports arrays of all shapes and sizes.

Using parameters has slightly changed - they are completely separated from traces and call sites. You have to pass them into contexts, and manage them yourself. This cleanly separates a number of things, and I think is a good design choice in the long run.

Furthermore, this is the first official release which supports the new tuple indexing notation/selection specification for addresses.

To specify a selection, there is a universal interface:

sel = selection([(:x, ) => 5.0, (:x, :y, 1) => 10.0])

Here, commas in the tuple separate different levels of the call stack.

Indexing is done in a similar way:

# Some call site
cl[:x, :y, 10]

says, access the the choice in call :x, in call :y, at address 10.

This choice has also significantly cleaned up some weirdness associated with using Pairs in addressing.

Addresses are now Any as well. So go wild.
