I get a compilation error if I call some case objects "r0", "r1" and so on. If I use different names, the code compiles and executes as expected. Rational for this would be very welcome!
code:
package qndTests2 sealed abstract case class Reg() trait RReg trait RRegNotPc extends RReg trait LowReg extends RReg sealed abstract case class LowRegClass() extends Reg with LowReg sealed abstract case class RRegNotPcClass() extends Reg with RRegNotPc case object R0 extends LowRegClass case object R1 extends LowRegClass case object R2 extends RRegNotPcClass case object R3 extends Reg with RReg sealed abstract case class Base() trait T1 trait T2 extends T1 trait T3 extends T1 sealed abstract case class CaseClassT3() extends Base with T3 sealed abstract case class CaseClassT2() extends Base with T2 case object r0 extends CaseClassT3 case object r1 extends CaseClassT3 case object r2 extends CaseClassT2 case object r3 extends Base with T1 object test { def regToInt(r: RReg): Int = { r match{ case R0 => 0 case R1 => 1 case R2 => 2 case R3 => 3 } } def toInt(r: T1): Int = { r match{ case r0 => 0 case r1 => 1
the package "qndTests2" contains only one Test.scala file, and the full contents of the file are indicated above. Replace "r0" ~ "r3" with "A" ~ "D" and it will compile! I am not the reason why ... I am just very tired without noticing anything obvious ???
