Design Philosophy

• Modern Language features (Range, Slice).
• Strong Typed - but easy syntax.

But nothing radically new. Should look familiar.

• No hidden memory allocation.
• No hidden function calls.
• No implicit conversions.

Syntax directs thought. The way you write it down should match with the underlying model.

• Simple to learn.
• Minimal number of keywords.
• Singular meaning (as much as possible) / one way to do things.
• Easy to build (parse).

What is better in Z# than other languages?

• More consistency. Operators generally mean only one thing.
• Less noise. No unnecessary keywords and no brackets or semi-colons.
• Focus on compile-time benefits. Do as much at compile-time as possible (meta-programming).
• Just data and functions. You can do sort of OO but not full OOP. Makes it simpler to learn and the resulting constructs translate easier to (simpler/smaller/faster) machine code.

Goals

• Stable and consistent syntax for refactoring code units to other scopes. Lifting a local function out => making it public (export) etc.

Explain: size, length, count, capacity.
