Research direction
Start at the Effect.fnUntraced entry point and compare its public API with Effect.fn, focusing on how the { self: this } overload is represented. Then find the existing tests for these APIs and add coverage showing that class methods can use the proposed form; done means the new usage type-checks and the tests pass.
Written by the indexing model from the issue text.
Description
What is the problem this feature would solve?
-
using
Effect.fnUntraced()to define class methods (when tracing is not needed) -
consistency with
Effect.fn()API (I ran into this when I realized I didn't needEffect.fn()and refactored some usages toEffect.fnUntraced())
What is the feature you are proposing to solve the problem?
Effect.fnUntraced() should accept a { self: this } overload the same way that Effect.fn() does
