AsyncIterableX.pipe fallback overload is unexpectedly chosen

[andreasdamm-shure]

The most generic AsyncIterableX.pipe overload

IxJS/src/asynciterable/asynciterablex.ts

Line 447 in 4a1d9c8

pipe(...operations: OperatorAsyncFunction<any, any>[]): AsyncIterableX<any>;

can end up being chosen by the TypeScript compiler in unexpected circumstances leading to type errors being missed due to an AsyncIterableX of any being returned.

The following function exhibits this behavior:

import { of } from 'ix/asynciterable/index.js';
import { map, tap } from 'ix/asynciterable/operators/index.js';

export function subscribe(): AsyncIterable<{ brand: 'X' }> {
   return of(undefined).pipe(
      map(event => ({ brand: 'Y' })),
      tap()
   );
}

The overload should be removed or at the very least should return an AsyncIterableX of unknown.

Removing the overload also fixes #377.

The fallback overload for IterableEx is also different from the one for AsyncIterableEx

IxJS/src/iterable/iterablex.ts

Line 215 in 4a1d9c8

pipe<R>(...operations: OperatorFunction<T, R>[]): IterableX<R>;
