Can we define implicit conversions of enums in c#?
... }
public static class MyEnumExt
{
public static int Value(this MyEnum foo) { return (int)foo; }
static void Main()
{
MyEnum val = MyEnum.A;
int i = val.Value();
}
}
This doesn't give you a lot, though (compared to just doing an explicit cast).

Why use symbols as hash keys in Ruby?
...troduced a simplified syntax just for hash with symbols keys (e.g. h.merge(foo: 42, bar: 6)), and Ruby 2.0 has keyword arguments that work only for symbol keys.
Notes:
1) You might be surprised to learn that Ruby treats String keys differently than any other type. Indeed:
s = "foo"
h = {}
h[s] = ...
How can I know which parts in the code are never used?
...sis using the AST of the entire program is the way to get it. (Preventing foo() from being marked as "called" when it appears only in if (0) { foo(); } would be a bonus but requires extra smarts.)

How to overload std::swap()
...this issue I really don't like the method you advocate because if I define Foo and swap that way someone else who uses my code is likely to use std::swap(a, b) rather than swap(a, b) on Foo, which silently uses the inefficient default version.

How does HashSet compare elements for equality?
...sidered equal"). This is almost never implemented on the type itself (i.e. Foo doesn't implement IEqualityComparer<Foo>) but in a separate type which is only used for comparisons.
Implement equality in the type itself, by overriding GetHashCode and Equals(object). Ideally, implement IEquatable...
How do I control how Emacs makes backup files?
Emacs puts backup files named foo~ everywhere and I don't like having to remember to delete them. Also, if I edit a file that has a hard link somewhere else in the file system, the hard link points to the backup when I'm done editing, and that's confusing and awful. How can I either eliminate th...

How to recover stashed uncommitted changes

Thus, when you ran git stash, you might have edited both files foo and zorg, but only staged one of those.
So when you ask to get the stash back, it might be nice if it git adds the added things and does not git add the non-added things. That is, if you added foo but not zorg back befor...
How can I discard remote changes and mark a file as “resolved”?
