--- Comment #5 from Manu <turkey...@gmail.com> --- > dmd -m64 main.d Emits: main.obj : error LNK2019: unresolved external symbol _D4test9test_funcFiiZv referenced in function _Dmain (expected) main.obj : error LNK2001: unresolved external symbol _D3std5range__T3ZipTAAyaTQfZQn6__initZ (WTF?) I think you've missed my point, there is NO REFERENCE to Zip!().init in main.d, at least, there shouldn't be... so why the link error? Where is the reference coming from? --
