My goal is to have the best documentation for each provided type.

If something is unclear in any of the types, please comment or open a PR to improve it.

Some things you could contribute:

• Fix typos.
• Improved description of the type.
• More examples.
• Provide more real-world use-cases. This helps the user understand where a type might come in handy.
• Add links to relevant discu

e.g.

# map.py
def func(a: int) -> float:
    return float(a)

map(func, ['str'])

$ pytype map.py

# typed: true
extend T::Sig

x = T.let(nil, T.nilable(Integer))
T.reveal_type(NilClass.===(x))

T.reveal_type(NilClass.===(T.unsafe(nil))

With #235 I've noticed that InstanceOf is undocumented in the readme.

Currently pgTyped CLI package is using minimist for CLI flag parsing. By design minimist is rather minimal and doesnt provide any advanced features.

To improve the current CLI experience we should switch to yargs.

Things we will get out of the box with yargs:

• Help command
• Env variable support
• Flag value validation
• Documented default values

It's easy to forget to support dict subclasses when adding primitives, so it would
be good to have test cases that override all dict methods (and check that the
overridden implementations are used) to make sure this works as expected.

Note that until mypyc supports some additional dunder methods, this can't be
fully implemented.

Debugging Kotlin∇ code within IntelliJ IDEA can be somewhat cumbersome due to the functional API structure (lots of deeply-nested stack traces and context switching). To facilitate more user-friendly debugging, we should add support for visual debugging by exposing Kaliningraph’s built-in graph visualization capabilities. For example, the use

(exp (log (make-polar 1.7976931348623153e+308 -1.797693134862315e+308)))

produces -8.648665413126592e+306-1.7956115019091953e+308i in Racket but -inf.0-inf.0i after Typed Racket optimization. Optimized code is:

(let-values (((g3)                                        
                    (#%app
