In a named function, we declare the parameters and return type in the func declaration line. func say(s:String)->() { // body } In an anonymous function, there is no func declaration line – it’s anonymous! So we do it with an in line at the start of the body instead. { (s:String)->() in // body … Read more
I’ve come across the following resources on my travels (some already mentioned above): HTML Mark-up-focused search engines Nerdydata I’d also like to throw in the following: Huge, website crawl data archives Common Crawl – ‘years of free web page data to help change the world’ (over 250TB+) How can we analyze this crawl data?

cref is meant to refer to another member – a class, a method etc. What would you expect it to link to in this case? In general, what do you want the overall effect to be? According to this excellent XML doc guide, the <see> tag has an undocumented attribute langword: <see langword=”switch” /> Would … Read more
It’s Friend. See the MSDN documentation.
inline is the keyword, in C++ and C99. __inline is a vendor-specific keyword (e.g. MSVC) for inline function in C, since C89 doesn’t have it. __inline__ is similar to __inline but is from another set of compilers. __forceinline is another vendor-specific (mainly MSVC) keyword, which will apply more force to inline the function than the … Read more
It’s because is is a reserved keyword in Kotlin. Since Kotlin is supposed to be interoperable with Java and is is a valid method (identifier) name in Java, the backticks are used to escape the method so that it can be used as a method without confusing it as a keyword. Without it it will … Read more
In C++11, auto has new meaning: it allows you to automatically deduce the type of a variable. Why is that ever useful? Let’s consider a basic example: std::list<int> a; // fill in a for (auto it = a.begin(); it != a.end(); ++it) { // Do stuff here } The auto there creates an iterator of … Read more
You could use a labeled BREAK statement: search: for (i = 0; i < arrayOfInts.length; i++) { for (j = 0; j < arrayOfInts[i].length; j++) { if (arrayOfInts[i][j] == searchfor) { foundIt = true; break search; } } } However, in properly designed code, you shouldn’t need GOTO functionality.
There is no final equivalent in Python. To create read-only fields of class instances, you can use the property function, or you could do something like this: class WriteOnceReadWhenever: def __setattr__(self, attr, value): if hasattr(self, attr): raise Exception(“Attempting to alter read-only value”) self.__dict__[attr] = value Also note that while there’s @typing.final as of Python 3.8 … Read more
I found this in a blog: “What does this C# code look like in F#? (part one: expressions and statements)” C# has an operator called “default” that returns the zero-initialization value of a given type: default(int) It has limited utility; most commonly you may use default(T) in a generic. F# has a similar construct as … Read more
