Claims for the paper

Conversions

• Most of the conversions are transitive.
• Transitive conversions are less dangerous than it seems.
  • They mostly convert to library types, not to primitives.
  • Most of them are used in DSLs.
• Non-transitive conversions usually have a low usage-rate.
• Most of them have 10 or less call sites.
