Synposis:
auto m = matchFirst("42 days", `[a-z]+`, `\d+`);
assert(m.index == 2); //2nd pattern match
assert(m.index != 0); //same as not empty
foreach(item; "42 days".matchAll(`[a-z]+`, `\d+`))
{
switch(item.index){
case 1:
assert(item[0] == "days");
break;
case 2:
assert(item[1] == "42");
break;
default:
assert(0);
}
}
Rationale - as a more efficient common basis for pattern matching (e.g.
switch-case on with regex patterns as cases).
