Not with local variables, but you can with a struct.
===
import std.stdio;
void main() {
struct Vars {
int x;
int y;
int z;
ref int get(string name) {
// allMembers gets the names of each member
as a string
foreach(member; __traits(allMembers, typeof(this))) {
// we're only interested in ints
because string++ doesn't make sense anyway
static if(is(typeof(__traits(getMember, this, member)) ==
int)) {
if(member == name)
return __traits(getMember,
this, member);
}
}
throw new Exception("I don't know " ~ name);
}
}
Vars vars;
writeln("which variable?");
vars.get(readln[0 .. $-1])++;
writeln(vars.x, vars.y, vars.z);
}
