Yes, that error is caused by a bug of
BitArray(https://issues.dlang.org/show_bug.cgi?id=13806).
Having "init" function broke template constraints of
"chain"(and must break dozen of other templates).
pragma(msg, ElementType!(BitArray[])) // prints 'pure nothrow
void(bool[] ba)' - ElementType uses "init" property to
determine types.
Thanks for this. If I recompile phobos with the pull request
(having edited out the init property entirely) then the code
mostly works.
However, I still can't use join, joiner, or chain on two
BitArrays. Eg
auto x=joiner(a,b).array;
I can chain two arrays of BitArrays, but not join or joiner them.
If this is what ought to happen, why?
