I'd like to know if there's a generic function over arrays to find the

int indexOf(S) (in S[] arr, S elem);
which works the same way the std.string.indexOf() function works...
couldn't find anything in the std.array module for this scenario.
Would be nice to have this functionality built-in somehow.
Or is there a completely different / better approach to this in D?
Thx, M.
countUntil in std.algorithm should work fine.

sizediff_t indexOf(alias pred = "a == b", R1, R2)(R1 haystack, R2 needle);
Scheduled for deprecation. Please use std.algorithm.countUntil instead.
Same as countUntil. This symbol has been scheduled for deprecation
because it is easily confused with the homonym function in std.string.

But isn't it the same funcionality? Why use a different name for the
same funcionality?
