A modern programming language that makes developers happier.

kotlinlang

We have a sum function for all the primitive types, but not for `BigDecimal`:
```listOf(1, 2, 3).sum()
listOf(1.toBigDecimal(), 2.toBigDecimal()).sum()  // Error
listOf(1.toBigDecimal(), 2.toBigDecimal()).sumOf { it }  // OK```
Since there is already a `sumOf` function specialized for `BigDecimal`, why isn't there a `sum` function for it too?

Good question. Would be as easy as
```fun Iterable&lt;BigDecimal&gt;.sum() = this.sumOf { it }```


I would recommend to report a feature request on Kotlin issue tracker
