What is java interface equivalent in Ruby?
... a class in Ruby that implements (enough of) IO, but I did it by trial and error and wasn't too happy with the process. I've also written multiple implementations of an interface of my own, but documenting which methods are required and what they are supposed to do so that other members of my team ...

What's the point of map in Haskell, when there is fmap?
...ical; when teaching Haskell to beginners the very general type of map made error messages more difficult to understand. In my opinion this wasn't the right way to solve the problem.
Haskell 98 is seen as a step backwards by some Haskellers (including me), previous versions having defined a more ab...

What are the differences between type() and isinstance()?
...g)

try:
return treatasiter(iter(x))

You could say that basestring is an Abstract Base Class ("ABC")—it offers no concrete functionality to subclasses, but rather exists as a "marker", mainly for use with isinstance. The conc...
Is it possible to make a type only movable and not copyable?
... the new struct or enum is itself Copy. If not, the compiler will print an error message. It can also only exist if the type doesn't have a Drop implementation.
To answer the question you didn't ask... "what's up with moves and copy?":
Firstly I'll define two different "copies":
a byte copy, w...
Who architected / designed C++'s IOStreams, and would it still be considered well-designed by today'
...rally considered
outdated.)
I would say NO, for several reasons:
Poor error handling
Error conditions should be reported with exceptions, not with operator void*.
The "zombie object" anti-pattern is what causes bugs like these.
Poor separation between formatting and I/O
This makes stream ob...
Should unit tests be written for getter and setters?
...is run as part of larger tests. The last pieces to be covered are probably error handling. And if the error handling isn't covered by unit tests it will never be covered. Do you really want to ship a product that contains code that has never ever been run?
