...duly hurt others.
Contrived Example: An empty virtual destructor on an array of one million small elements may plow through at least 4MB of data, thrashing your cache. If that destructor can be inlined away, the data won't be touched.
When writing library code, such considerations are far from ...
Why aren't python nested functions called closures?
...native way, as @unutbu pointed out, would be to define each variable as an array (x = [0]) and modify it's first element (x[0] += 1). Again no error arises because x itself is not modified.

dim(M) <- c(2,3) ...
How can I use interface as a C# generic type constraint?
...s a generic type and has a constraint, we check the constraint; if it's an array, we check the element type.
At this point I must add that this will break the fact that by default .NET loads types 'lazy'. By scanning all the types, we force the .NET runtime to load them all. For most programs this ...
