types

microsoft/TypeScript#45350 introduces the Awaited type, which does the same thing (but more advanced).

This is part of TypeScript 4.5.

Elm has the option to output errors as JSON (via a flag), and something like that is handy for writing tooling around it. I'm trying to integrate pytype into ALE and this would make it a lot easier.

# typed: true

class MyEnum < T::Enum
  enums do
    X = new
  # ^ def: X

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

I'd like to add a config and the ability to have a .js config file in order to generate nestjs repositories and files that just have types. The easiest way to do this, and without introducing much additional maintenance would be to let folks supply their own generator templates.

Splitting the types to a different library might be a little tricky to add in a config, so at first it might not b

These operations related to bytes values are either common or "fundamental" and worth dedicated primitives if they help with performance:

• + (concatenation)
• len(b)
• b[n] (indexing)
• ==, != (python/mypy#10928)
• <, <=, etc.
• b[:n] etc. (slicing) (python/mypy#10966)
• s.encode(<literal>) (for utf8, ascii and latin1)
• `s.encode(

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                                      
                     log              

It is common to have Union traits of the form Union(None, <something>). As a convenience to developers, and following a similar convention in Python's typing module, we should consider having Optional(<something>) as an alternative way of writing Union(None, <something>).

An alternative would be to make allow_none metadata universally accepted across TraitType instances.
