Unconverted Builder

[jubnzv]

Summary
An optional low-severity dead code detector that finds suspicious Builder objects which are not converted to Cell or Slice.

Context
The Builder object should be converted to Cell or Slice using .endCell() or standard library functions such as asCell() or asSlice(), or stored in another Builder using .storeBuilder(). If this is not done, it could indicate disruptions in the contract's logic and should be reviewed by the auditor.

Examples

fun storeValue(value: Int): Cell {
  let b = beginCell(); // Bad: Not converted to Cell
  b = b.storeInt(value, 16);
  return self.someCell; // Wrong value was returned
}
