(Sorry bearophile, don't mean to steal your thunder but since I'm writing some
D1 switch code right now, I may as well strike while the iron is still hot ...)
Speaking of switch statements, when switching on an enum type, e.g.
enum Color {
RED,
GREEN,
BLUE
}
void foo( Color color) {
switch (color) {
case Color.RED:
break;
case Color.GREEN:
break;
case Color.BLUE:
break;
}
}
Would it be possible for the compiler to infer the declared enum type, in this
case Color, making for abbreviation of the enum member names in the case
clauses as per the following?
void bar( Color color) {
switch (color) {
case RED:
break;
case GREEN:
break;
case BLUE:
break;
}
}
