Rewriting without any was evaluated; the alternatives were more
complex than the current solution. Record the rationale next to the
two oxlint-disable sites so the suppression is not re-litigated.
getPrimitiveUnionMatcherPartialW was declared with the intended
P-inferring signature but assigned via `as any`, hiding that the
declared parameter was not assignable to the implementation's. The
union in PatternPrimitiveUnionPartial makes the `_` arm demand
`_ ∈ keyof P`, which the exhaustive arm cannot prove.
Intersect the inference hook Simplify<P> with the implementation's
parameter shape, R pinned to PatternReturns<P>, so the assignment
type-checks while callers keep inferring P from the argument.
Add a spec for the exhaustive (no `_`) pattern.
Curried matchers over string|number literal unions in four variants
(exhaustive/partial x strict/widened return inference), per the header
matrix in src/primitive.ts.
- Adds type-fest for Simplify/ValueOf.
- Deliberate oxlint escape hatches (as any dispatch) until a cast-free
formulation lands; see the file comments.
