Expand description

Validate that a function has at most one return statement (suitable for inlining).

  • Arrow functions with expression bodies (no return keyword) → valid (single-return)
  • Functions with 0 returns (void) → valid
  • Functions with exactly 1 return → valid
  • Functions with >1 return → invalid, returns the count
