ZLint is a X.509 certificate linter written in Go that checks for consistency with standards (e.g. RFC 5280 (https://www.ietf.org/rfc/rfc5280.txt)) and other relevant PKI requirements (e.g. CA/Browser Forum Baseline Requirements (https://cabforum.org/wp-content/uploads/CA-Browser-Forum-BR-1.4.8.pdf)).

Halide is a programming language designed to make it easier to write high-performance image and array processing code on modern machines. Halide currently targets: * CPU architectures: X86, ARM, MIPS, Hexagon, PowerPC, RISC-V * Operating systems: Linux, Windows, macOS, Android, iOS, Qualcomm QuRT * GPU Compute APIs: CUDA, OpenCL, OpenGL Compute Shaders, Apple Metal, Microsoft Direct X 12 Rather than being a standalone programming language, Halide is embedded in C++. This means you write C++ code that builds an in-memory representation of a Halide pipeline using Halide's C++ API. You can then compile this representation to an object file, or JIT-compile it and run it in the same process.

Often, especially for package modules, you want to import names for convenience, but not actually perform the imports until necessary. The zope.deferredimport package provides facilities for defining names in modules that will be imported from somewhere else when used. You can also cause deprecation warnings to be issued when a variable is used.
