module Prelude
{-
The Prelude is minimal (since it is effectively part of the language
specification, this seems to be desirable - we should, nevertheless, aim to
provide a good selection of base libraries). A rule of thumb is that it should
contain the basic functions required by almost any non-trivial program.
As such, it should contain:
- Anything the elaborator can desugar to (e.g. pairs, unit, =, laziness)
- Basic types Bool, Nat, List, Dec, Maybe, Either
- The most important utility functions: id, the, composition, etc
- Interfaces for arithmetic and implementations for the primitives and
basic types
- Char and String manipulation
- Show, Eq, Ord, and implementations for all types in the prelude
- Interfaces and functions for basic proof (cong, Uninhabited, etc) --
- Semigroup, Monoid
- Functor, Applicative, Monad and related functions
- Foldable, Traversable
- Range for range syntax
- Console IO and interfaces for supporting IO
Everything else should be in the base libraries, and imported as required.
In particular, proofs of Nat/List properties that almost never get used in
practice would probably be better in base libraries.
Everything should be total, unless there's a good justification for it not
to be (division by zero, as a concrete example).
(These guidelines will probably get revised a few times.)
