# Standard library

## The `bool` module

- `bool.if`: Requires exactly 3 arguments of arbitrary type. If $0 is a truthy value, evaluate and return $1. If $0 is a falsy value, evaluate and return $2. Values considered as falsy are: `bool.false` and `nil.nil`. Everything else is considered truthy.
- `bool.and`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all of the arguments are considered truthy.
- `bool.or`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if at least one of the arguments is considered truthy.
- `bool.equal`: Accepts an arbitrary number of arguments of arbitrary type, but at least 2. Returns `bool.true` if either all of the arguments are considered truthy or all of the arguments are considered falsy.
- `bool.not`: Accepts exactly one argument of arbitrary type. Returns `bool.true` if the $0 is considered falsy, returns `bool.false` if $0 is considered truthy.
- `bool.true`: The true constant
- `bool.false`: The false constant
- `bool.is`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all arguments are booleans (`nil.nil` is NOT considered a boolean).

## The `:int` module

- `int.add`: Accepts an arbitrary number of integer arguments (or none at all) and returns the sum of all arguments, or `0` if none were given.
- `int.sub`: Accepts exactly 2 integer arguments and returns their difference.
- `int.mul`: Accepts an arbitrary number of integer arguments (or none at all) and returns the product of all arguments, or `1` if none were given.
- `int.div`: Accepts exactly 2 integer arguments and returns their quotient (rounded towards 0).
- `int.mod`: Accepts exactly 2 integer arguments and returns the reminder of their division.
- `int.smaller`: Accepts exactly 2 integer arguments and returns `bool.true` if $0 is smaller than $1, `bool.false` else.
- `int.greater`: Accepts exactly 2 integer arguments and returns `bool.true` if $0 is greater than $1, `bool.false` else.
- `int.equal`: Accepts an arbitrary number of integer arguments, but at least 2. Returns `bool.true` if all the arguments are equal.
- `int.is`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all arguments are integers.

## The `nil` module

- `nil.nil`: The nil constant
- `nil.is`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all arguments are strings.

## The `ref` module

- `ref.call`: Accepts a function reference as $0 and after that and arbitrary number of arguments of arbitrary type. Calls the function $0 with the arguments that follow and returns it's return value.
- `ref.is`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all arguments are function references.

## The `str` module

- `str.cat`: Accepts an arbitrary number of arguments of arbitrary type and returns the concatenation of their string representations.
- `str.is`: Accepts an arbitrary number of arguments of arbitrary type, but at least one. Returns `bool.true` if all arguments are strings.

### String representations

- Integers: decimal notation
- Strings: themself
- Function references: `[Function referece: %p]`, where %p is the memory address of the UwUVMFunction in memory.
- Nil: an empty string
- Booleans: `true` or `false`
