Timon Gehr:
mixin ADT!q{ Term: Var char | Op char Term[] };
void main(){
const expr = Op('f', [Op('g',[Var('x'), Var('y')]),
Op('a',[]), Var('x')]);
}
Where is ADT defined? (And why isn't it a Phobos patch on GitHub?)
convertNum could be written more compactly as:
char convertNum(int x){
return "exyzfgh"[x<$?x:0];
That's too much compact :-) Humans put a space around operators,
and sometimes some parentheses don't hurt:
char convertNum(in int x) pure nothrow
in {
assert(x >= 0);
} body {
return "exyzfgh"[(x < $) ? x : 0];
}
