Primitive type capitalization

Feature Spec

This is a proposal to change all built-in types to use lowercase instead of PascalCase, so they all have a similar look and feel, and are also distinguishable from user-defined types.

So basically the lowercase versions are just aliases:

• str
• num
• bool
• duration
• date
• json
• array<T>
• set<T>
• map<T>
• mutarray<T>
• mutset<T>
• mutmap<T>

Use Cases

To reduce cognitive load, all types should have a similar look & feel.

As an example, see the spec for Json, which proposes the all built-in types will have a from_json() method.
