Damn, that's really cool. I noticed that a lot of your tools 
followed this pattern:

```d
@Tool("Count how many times substring appears in text.")
string nOccurrences(string text, string substring) {
   try {
     return to!string(text.count(substring));
   } catch (Exception e) { return(format("Error: %s", e.msg)); }
}
```

Did you know that you can use 
[std.exception.ifThrown](https://dlang.org/library/std/exception/if_thrown.html) to simplify this down to:

```d
@Tool("Count how many times substring appears in text.")
string nOccurrences(string text, string substring) {
     return text.count(substring)
                .to!string()
                .ifThrown(e => "Error: %s".format(e.msg));
}
```

I love how you can write such elegant, concise code in D.
