Better Python Object Serialization. TIL about functions.singledispatch, a decorator which makes it easy to create Python functions with implementations that vary based on the type of their arguments and which can have additional implementations registered after the fact—great for things like custom JSON serialization. # 7th January 2020, 8:35 pm

There is plenty of evidence in the ecosystem to support the hypothesis that, if given the tools to do so easily, object-oriented programmers are ready to embrace functional techniques (such as immutability) and work them into an object-oriented view of the world, and will write better, less error-prone code as a result. Simply put, we believe the best thing we can do for Java developers is to give them a gentle push towards a more functional style of programming.

php: rfc: closures (via) I never thought I’d see the day, but a patch adding closures to PHP has been both proposed and accepted! Looks like a solid implementation—the syntax is similar to JavaScript but makes explicit which variables are to be captured. As with much of PHP, values are copied in to the closure by default but you can use an ampersand to specify JavaScript-style pass-by-reference instead. # 19th July 2008, 10:58 pm
