Now, adding Maybe to a result type without a reason would only make the code more confusing and no safer. The type signature of a function with unnecessary Maybe would tell users of the code that the function could fail when it actually can't. Of course, that is not as bad a lie as the opposite one (that is, claiming that a function will not fail when it actually can), but we really want honest code in all cases. Furthermore, using Maybe forces us to propagate failure (with fmap or monadic code) and eventually handle the failure cases (using pattern matching, the maybe function, or fromMaybe from Data.Maybe). If the function cannot actually fail, coding for failure is an unnecessary complication.


If you want to allow missing properties, use optional property syntax, where the ? is placed before the colon.It is also possible to combine both syntaxes for an optional maybe type, for example value?: ?number.

Another advantage of using a maybe value for these situations is that, since thereturn value is wrapped, the user of that function is forced to acknowledge thepossibility of an error, as the value can't be used directly.

The translation for magari which learners find easiest to comprehend is maybe or perhaps. Used in this sense, it is more or less interchangeable with the adverbs forse and può darsi (che).

Similar to maybe but for use in cases where the default value may beexpensive to compute. As PureScript is not lazy, the standard maybe hasto evaluate the default value before returning the result, whereas herethe value is only computed when the Maybe is known to be Nothing.

Source.maybe has some similarities with Source.fromFutureSource.fromCompletionStage. One difference is that a new PromiseCompletableFuture is materialized from Source.maybe each time the stream is run while the FutureCompletionStage given to Source.fromFutureSource.fromCompletionStage can only be completed once.

The Source.maybe[Int] will return a Promise[Option[Int]]CompletableFuture materialized value. That PromiseCompletableFuture can be completed later. Each time the stream is run a new PromiseCompletableFuture is returned.

The song is irresistibly catchy, has spurred countless online parodies and become a full-blown craze, with everyone from Justin Bieber and Selena Gomez, to Katy Perry, the Harvard baseball team, SMU women's rowing team and others belting out the lyrics in their own lip-syncing spoofs. A Corgi called "Corgi Rae Jepsen" has barked out the beat and even Cookie Monster has gotten involved, tweeting: "Me just met you. Dis is crazy. But me love cookies! Gimme, maybe?"

Simkin said, "The lyrics are such a hook - not just the call me maybe line, but 'Before you came into my life/I missed you so bad.' I have had so many people tell me that those words really speak to them."

Often they go unnoticed, he said, but put " a slight 'something's not quite right' thought in the back of the listener's mind," and therefore stick. Jepsen's hit is filled with incongruities. Take the hook: "Hey, I just met you, and this is crazy, but here's my number, so call me, maybe?" 041b061a72
