When I execute it, I'm getting a range violation error. If I

Because you're indexing the prompt with i before you ensure
that i is valid. Swap the operands in your if condition:
```
while (i < len && prompt[i] != '{')
```
Or better yet, use foreach, which exists to avoid this sort of
mistake:
```
foreach(c; prompt) {
if(c != '{') printf("%c", c);
}
```
OMG!!! Yes! I feel bad for not catching it now... Meanwhile I
realized "while" will not work in my example anyway. Thanks for
the man! Have a nice day!
