StaticArray.slice: ERROR TS2304: Cannot find name 'T'.

[ckaznocha]

While updating from v0.20.18 to v0.20.19 I started getting a TS error from staticarray.ts

ERROR TS2304: Cannot find name 'T'.
     :
 235 │ slice<U extends ArrayLike<T> = Array<T>>(start: i32 = 0, end: i32 = i32.MAX_VALUE): U {
     │                                      ~
     └─ in ~lib/staticarray.ts(235,40)

I suspect this may be related to #2404.

I have some functions that slice a StaticArray. A simple example may be something like:

export function foo(a: StaticArray<string>): string[] {
  const result = a.slice(0);
  // push some things onto "result"
  return result;
}

With v0.20.18 I would not get any TS errors.

Thanks for report! Can confirm.
Currently, you can use this workaround:

export function foo(a StaticArray<string>): string[] {
  const result = a.slice<string[]>(0);
  return result;
}

Should be fixed in 0.21.1

Thanks @MaxGraey, @HerrCai0907 and @dcodeIO! The errors are gone now.
