Also known as BLT, blit refers to copying memory byte for byte. In C, this is referred to as a memcpy operation. The name originated with the BLT instruction on the DEC PDP-10 computer.

Refers to the ability to execute regular D functions at compile time rather than at run time.

In Unicode terminology, a code point is a logical character. The range of code points is 0 through 0x10FFFF. Only dchars can store code points directly; arrays of char and wchar need to use the va [..]

COW is a memory management strategy where (usually large) reference objects are copied if they are to be modified. The constant overhead of COW can be high, but may be preferable in applications tha [..]

Two or more threads writing to the same memory location. Program behavior may depend on the arbitrary sequencing of these memory accesses.

A user-defined type (struct or class) that defines the function call operator (opCall in D) so it can be used similarly to a function.

Garbage collection is the common name for the term automatic memory management. Memory can be allocated and used, and the GC will automatically free any chunks of memory no longer referred to. In c [..]

A function that either accepts another function as a parameter, returns a function, or both.

Refers to the ability to instantiate a template function without having to explicitly pass in the types to the template. Instead, the types are infered automatically from the types of the runtime argu [..]

A code construct is illegal if it does not conform to the D language specification. This may be true even if the compiler or runtime fails to detect the error.
