I believe, I have a function that is good candidate to be in

Feedback is appreciated.
Hi Igor,
Some remarks:
1- I guess that when t is the empty string you should return true, not
false: the empty string is present in any string. So your first static
if should be cut in two.
2- the .found necessary to get the result could be hidden with a
two-levels template:
template substring(string s, string t)
{
enum bool substring = substringImpl!(s,t).found;
}
and rename your substring into substringImpl. Then you can do:
auto s = substring!("fun with gun", "run");
I don't know if you can put substringImpl as a private template inside
substring?
3- Maybe you could do a (string s, char c) version which casts the char
into a string and look for it.
Philippe
