Counting number of regular expressions matches

[Alain De Vos via Digitalmars-d-learn]

I've got,
import std.regex: regex,matchAll;
...
string regfiltertext="\\b"~entryfilter.getText()~"\\b";
auto reg = regex(regfiltertext);
auto result = name.strip("_").matchAll(reg);
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 ?
