Gotchas

Function suffixes

• _: These are the uncurried versions of the function with the same name.
• _M: Monadically. Meaning the passed mapper function is applied with chain instead of map.
• `unsaf

Importing types

Generally it is advised to import types like import { Option } from "@effect-ts/core/Option", even if you import the rest of the module like import * as "@effect-ts/core/Option". It keeps the type signatures leaner.

When to use Fully Qualified Module names when accessing functions

e.g MO.props over props:

Whenever the majority purpose of the module, is not to work with the imported module S. Aka. if a module is all about defining Schema types, you would not import * as S but import { props }

When to use inline pipe ["|>"] over multi-line pipe

Basically as the title says: for quick, often short, inline pipes, use ["|>], but for longer more steps, multi-line pipes, prefer pipe
