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?
