Covers a bug with ape. The regex pattern used for checking if a returned data type is array or not does not cover uint256[20]
at least (and maybe more?).
To install:
python -m venv venv
source ./venv/bin/activate
pip install --upgrade pip
pip install -r ./requirements.txt
To reproduce this issue:
ape test
All tests should pass, which means you reproduced the issue.
