Custom getter without return on all paths compiles nevertheless












3















I wrote this code:



var test: String? = null
get() {
field?.also {
return "has value"
}
}


It reaches return only when the field is non-null. Otherwise the body just completes. Nevertheless, this compiles fine and returns null if field is null.



If I change to this:



var test: String? = null
get() {
if (field != null)
return "has value"
}


now the compiler complains that the block body needs a return statement.



Is this some undocumented feature or a bug?

          This is indeed a bug, planned to be fixed in 1.3.20.
