The conversation involves two users discussing a feature of the Effect TypeScript library related to streams. A user named @dan_connector has been exploring the library and is particularly interested in a solution for a debounced stream shared by @don_corleone076. They notice that before a stream is split, its type is A | symbol, but after the split, it becomes a type A stream. The issue is that the split operator currently only accepts a predicate, and they want to modify it to accept a refinement.
The suggested type changes:
Allow a predicate that acts as a refinement from A to a subtype B (extending A).
Update the split operator to use these refined types.
@don_corleone076 responds, expressing willingness to review the suggestion but notes that they are not completely familiar with the specifics of Stream.aggregate and suggests there might be a better type-level fit.
Key Takeaways:
The split operator currently accepts predicates, but there's interest in enhancing it to accept type refinements for better type accuracy.
Implementing changes requires understanding the internal workings of related components like Stream.aggregate.
