Lesson 1 · On the house

Template constraints and static if

Restrict templates with if constraints, branch at compile time with static if, and is expressions.

Lesson 2

Compile-time function evaluation

CTFE: run ordinary functions at compile time through enum, static, and template arguments.

Lesson 3

Mixins

String mixins compile generated code; template mixins paste reusable declarations into a scope.

Lesson 4

Compile-time reflection

__traits and std.traits: list members, inspect fields and attributes, and build generic serializers.

Lesson 5

The std.range toolkit

iota, chain, zip, enumerate, chunks, stride, cycle, retro, and lockstep for composing sequences.

Lesson 6

Function attributes

pure, nothrow, @safe, @trusted, @system, @nogc, and attribute inference for templates.

Lesson 7

Memory without the GC

Stack allocation, malloc/free from core.stdc.stdlib, scope classes, GC control, and RAII cleanup.

Lesson 8

Message-passing concurrency

std.concurrency: spawn threads, send and receive typed messages, ownerTid, and shared data rules.

Lesson 9

Data parallelism

std.parallelism: parallel foreach, taskPool.amap and reduce, tasks, and choosing work unit sizes.

Lesson 10

Struct lifetime and RAII

Destructors, copy constructors, @disable this(this), move semantics, and deterministic cleanup.
