I introduced a new type of CFG instructions, similar to ConditionalInstruction, called RefutablePatternInstruction. The idea is that every pattern that can possibly fail to match is surrounded with a pair of such instructions, helping to describe how the control flow moves in each case. The PEP calls the opposite type of patterns that always match "irrefutable", hence the name. We need these synthetic instructions because otherwise some refutable patterns such as literal ones (e.g. "42") don't leave any nodes in the graph. Incorporating the information about irrefutable patterns right into the graph allows catching cases such as "wildcard/name capture makes remaining patterns unreachable", both in OR patterns and independent case clauses.

Building the Python Plugin
To build the Python plugin for IntelliJ IDEA Community Edition:
-
Download the .tar.gz distribution of the most recent EAP or release build of IntelliJ IDEA Community Edition;
-
Run the following command:
ant -Didea.path= -Didea.build.number=<build number of the build you're using> plugin
The .zip file of the built plugin will be placed at distCE/python-community-.SNAPSHOT.zip
