I want to know whether the string strs contains

I can do : int index =
indexofany(strs,["exe","dll","a","lib"]);
but in D: I must to do like this:
findStr(strs,["exe","lib","dll","a"]))
bool findStr(string strIn,string[] strFind)
{
bool bFind = false;
foreach(str;strFind)
{
if(strIn.indexOf(str) !=-1)
{
bFind = true;
break;
}
}
return bFind;

phobos 's string.d can add this some function to let the
indexOfAny to better?
Thank you.

std.algorithm.canFind will do what you want, including telling
you which of ["exe","lib","dll","a"] was found.
If you need to know where in strs it was found as well, you
can use std.algorithm.find
Sorry, 'std.algorithm.find' do this work:Finds an individual
element in an input range,and it's Parameters: InputRange
haystack The range searched in.
Element needle The element searched for.
std.algorithm.find has several overloads, one of which takes
multiple needles. The same is true for std.algorithm.canFind
Quoting from the relevant std.algorithm.find overload docs:
"Finds two or more needles into a haystack."
