Method IsPipeableType

internal/typeparser/pipeable.go:10–25

IsPipeableType returns true if the type has a callable "pipe" property, indicating it supports the pipeable pattern (e.g., value.pipe(f1, f2, ...)).

// IsSafelyPipeableCallee returns true if a callee expression can be safely
// extracted into a pipe argument without losing `this` context.
// This is used by the missedPipeableOpportunity rule to determine which
// call expressions can be converted to pipe style.
