I found that function mod2pi is not implemented yet, but mod works. Is there any list of implemented functions? Minimal working example is:

using Zygote

# This is working
gradient(x -> mod(x, 2pi), 1.)

# This is not
gradient(x -> mod2pi(x), 1.)

It will be good to analyze var_dump leftovers in project, and to add support for other functions that cause same behavior.

I've selected Ggnn.init(vocabulary,node_y_dimensionality,graph_y_dimensionality,graph_x_dimensionality,use_selector_embeddings,test_only,name) for refactoring, which is a unit of 72 lines of code and 7 parameters. Addressing this will make our codebase mo

Currently the tests are all in folders pos and neg.

Instead, we could organize them by topic:

• syntax
• handlers
• stdlib
• ...

and add additional README.md files to the folders guiding newcomers. Additionally, the tests could have comments explaining the features.

This way we could have a low cost documentation that is automatically checked
