• Parse all return types of functions through PHPDoc
• Parse all return types of functions implicitly through return statements. PHPDocs take precedence.
• Type polymorphism through if, foreach etc. statements

Object Oriented Programming

• Inheritance constraints verification
• Inheritance type check

Aniruddh Agarwal blogged A short tour of PHP, and this is one of the negatives he identified:

Community: I know. I said that PHPs community was an advantage to it, but it is also a disadvantage, because of BAD CODE. Beginners are not taught the best practices and they go on to write bad code and distribute it, either as answers on Stack Overflow or similar websites or blog about it, which encourages other beginners to adopt those practices. There is a lot of misinformation out there, and it is very difficult to separate the good from the bad. This is perhaps the worst thing about PHP, because PHP is an entry-level language and people learning it are usually not aware of the best practices.

This is spot on!

The existence of BAD CODE being copied and pasted by newcomers is probably the biggest source of exploitable security vulnerabilities in the entire industry.

The biggest offenders are often the highest ranking search results on Google and other search eng

Compare speed of a cython wrapper vs a cffi wrapper to the same underlying
C-code with a fast function and a longer-running function.

This should run anywhere that has cffi and cython installed.

Spurred by recent events (https://news.ycombinator.com/item?id=8244700), this is a quick set of jotted-down thoughts about the state of "Semantic" Versioning, and why we should be fighting the good fight against it.

For a long time in the history of software, version numbers indicated the relative progress and change in a given piece of software. A major release (1.x.x) was major, a minor release (x.1.x) was minor, and a patch release was just a small patch. You could evaluate a given piece of software by name + version, and get a feeling for how far away version 2.0.1 was from version 2.8.0.

But Semantic Versioning (henceforth, SemVer), as specified at http://semver.org/, changes this to prioritize a mechanistic understanding of a codebase over a human one. Any "breaking" change to the software must be accompanied with a new major version number. It's alright for robots, but bad for us.

SemVer tries to compress a huge amount of information — the nature of the change, the percentage of users that wil
