Andrei, I agree that "with" is dangerous when it shadows outer names
(Python designers have not added a "with" because of this).
They did, but with different semantics =)
It's used for RAII (I guess you already know that, but maybe other
people
don't).
You mean like C#'s "using"?
What a God awful feature. Honestly, "what were they sinking about?"
People who explained that C# is cool - please explain this one.
Had to look it up, never used it.
Not sure it's that terrible, it looks to be the equivalent in D of:
{
scope C = new C();
...
}
I suppose it's good in cases where you want to have somewhat manual
memory management. Does seem poorly named though.
Or transactions, or locking, or similar things.
One of the interesting uses of it that I've seen is in Rhino Mocks:
using (Mocks.Ordered())
{
everything in this block records expected calls where the order matters
}
but over here, order doesn't matter.
