I've got,

int t=0;
foreach (c; result) t+=1;
This make t the number of regular expressions matches.
Is there a better way to have the number of matches ?
`matchAll` returns `RegexMatch` which is a ForwardRange, so it
should be possible to get it's length using `walkLength`.
```d
auto r = regex(`([a-z])a`);
auto result = "banana".matchAll(r);
writeln(result); // [["ba", "b"], ["na", "n"], ["na", "n"]]
writeln(result.walkLength); // 3
```
I'm not familiar with using matches with `std.regex`, but I hope
this solves your problem.
