Names matter.ActivateThinking Fast and Slow’ssystem 2way in which the brain forms thoughts and put some actual, careful thought into variable and method names. The few extra seconds can pay significant dividends. A well-named variable can make the code much more intuitive, whereas a poorly-nam...
So if there's an Eq class constraint for a type variable in a function, it uses == or /= somewhere inside its definition. All the types we mentioned previously except for functions are part of Eq, so they can be tested for equality....

When named capturing was first introduced, it required that all(?<name>...)captures use unique names. However, there are cases when you have multiple alternate paths through a regex, and it would simplify your code to reuse the same group names in each alternative. ...

Put simply, this means your wrapper should smell like language in which it is written — Ruby like Ruby, Java like Java, PHP like PHP, and so on. This usually comes into play when language conventions bleed through an API in the form of method and variable names. Take the following ...
