as expected.

Here i want to transform string into list of tuples split by 
character:

auto nameparts = splitter("go.home", '.').map!(v => 
tuple(v,0)).array;

This gives me not very useful message about assert and stuff:
core.exception.AssertError std.algorithm(1942): Assertion failure

It works for me:

     auto nameParts = "go.home"
                      .splitter('.')
                      .map!(v => tuple(v, 0))
                      .array;

     nameParts.writeln;
}


Output:

[Tuple!(string, int)("go", 0), Tuple!(string, int)("home", 0)]

I am using dmd 2.065alpha on Windows.

Hi Dfr. It's a known (and fixed) bug.

If you need to workaround it, you can use a named struct instead, 
something like:

struct TSI{string s; int i;}
auto nameparts = splitter("go.home", '.').map!(v =>
TSI(v,0)).array;
