what-color-is-your-function/ a joyfull rant about async functions and promises.<p>I like to request your comment on a similar topic. While coding in go - I often find me asking: is this package go-routine save? Many times I find the answer in the doc's or can ask on the internet, sometimes I need to look at the code.<p>"go routine safety" is just like the color in the rant of munificent.<p>On a current project I would like to assert that a user provided callback is a pure function - there we got another color!<p>those two colors are alike - they represent meta informations about an entity (function, package, struct) and they are about the behavior of the entity.<p>They also have something to do with boundarys - tho my English skills deny me to elaborate :(<p>I wounder...<p>Do you know other kinds of colors?<p>Is that coloring bothering you? And if not how do you approach it?
