I also had to ask because I couldn't find it. In other
languages it's named "index()", "indexOf()" or "find()". D is
the only language I know which uses the "countUntil" scheme.
And even so it's not obvious from the name if it's the index
of the element or number of preceding elements.
I had first tried myarray.index(myvalue) because I coulda sworn
I wrote exactly that syntax a only a few days ago. But I've
been hopping between languages, some D, some Crystal, some C++,
some Javascript, and with only two cerebral hemispheres, maybe
I got confused. So, D doesn't have index()? Is it called
find()? Something else? It was hard to find the right stuff
in the documentation.
You may have used indexOf, which works with strings. Why not
anything else? No idea, as it really should work with other
arguments.
