Proposal for strict matching comprehensions

Background

for comprehensions are one of the most powerful features in Elixir. It supports both enumerable and bitstring generators, filters through boolean expressions and pattern matching, collectibles with :into and folding with :reduce.

One of the features are automatic filtering by patterns in generators:

Hex Dependency Cooldown — Design

Date: 2026-04-29

Status: Design proposal (user facing design only; internal implementation deferred)

Background

Recent supply-chain attacks against package registries (npm, PyPI, RubyGems) have followed a recurring pattern: a maintainer's credentials are compromised or a dormant package is taken over, a malicious version is published, and automated dependency tooling pulls it into thousands of downstream projects within hours — well before the release can be reported and either flagged, retired or removed. Analyses of these incidents observe windows of opportunity under a week between publication and detection.
