Suggestion Backlog Slog, 8/6/2018 #26241
Description
- Proposal: Variadic Kinds -- Give specific types to variadic functions #5453 Variadic kinds - what use cases remain here?
- Disallow expressions of type
voidto be used in truthiness checks #26234 Disallow truthy checks of void - out of range index in a tuple magically works #5203 Disallow OOB access on tuples
- Polymorphic "this" for static members #5863 Static polymorphic
this - T[K] should be never when T is never #23005
T[K]should beneverwhenKisnever - Using string enum as key in {[key]: Type} throws not an index signature #22892
stringenumobject should be indexable type - esModuleInterop should work even when compiling to esnext modules #22851
esModuleInteropshould work whentarget=esnext - Abstract classes that implement interfaces shouldn't require method signatures #22815 Abstract classes that implement interfaces shouldn't require method signatures
- Casting to Partial<x> seems to be errorful #22806
Partial<T>should be a weak type - parameter initializer is bound to the wrong variable #22769 Allow unshadowed parameter initializer references in ES6+
- Typing number of children in TSX #22759 Let JSX children be subject to tupleness
- Bitwise enum initializer: compile-time constant but not allowed as a type reference? #22709 Allow references to literal-ish-initialized enums in type positions
- Proposal: Overload Function.bind for when no argArray is provided. #22669 Add a new overload to
Function#bind - Proposal: Easier Migration with Loose Mode in TypeScript Files #22665 Add a mode to make TS act like JS
- tsconfig cannot be specified along with an explicit list of files to compile - TS5042 #22649 Combine tsconfig with file list
- Inferred type symbol in conditional type should be visible-but-banned in falsy arm #22610 Keep
infervariable in scope in false arm of conditional type - Proposal: better type narrowing in overloaded functions through overload set pruning #22609 Do some type guards based on overload when a good discriminant is present
- Provide a back-compat mechanism for bundled .d.ts files in package.json #22605 Provide a back-compat mechanism for bundled .d.ts files in package.json
- typeof union.membername errors. #22598 Allow speculative union type property access in
typeof(expression) operands - Mapped types enumerating keys in
stringbehave poorly #22509 Something something mapped types - Any number can be assigned to enum member type #22311 Error on out-of-scope literal assigned to enum
- Allow bitwise test on
undefined#22230 Allow implicitundefined->0coercion understrictNullChecksfor bitwise ops - foo.ts is resolved before foo.d.ts even if the latter is in files[] #22208 Prefer .d.ts over .ts if it's in
filesarray - "...args: infer" on an overloaded function chooses only one function head #26136 Arg union type inference for overloads
- Add a strict flag forbidding impossible generic declarations #26129 Forbid illogical generic declarations

Wounded in action?

Well, it's accepted
Wondering if actionable
We're imitating ActionScript
