I get the error below with code like this:

What's wrong here? I import std.algorithm, std.range, std.array,
std.conv in the module.
(.data._D65TypeInfo_xC3std5range10interfaces18__T10InputRangeTiZ10InputRange6__initZ+0x10):

`_D64TypeInfo_C3std5range10interfaces18__T10InputRangeTiZ10InputRange6__initZ'

This linker error is saying it can't find a required typeinfo
initializer for std.range.interfaces.InputRange (of some type, not an
expert in demangling D symbols).
Generally this happens when you compile against a third-party library
file but don't link to it (I think that type of symbol is stored in the
module info).
Your posted code has nothing to do with this, so I'm not sure this is
the exact line you are having trouble with. Your posted map line should
not be invoking this error at all.
Have you tried Vladimir's DustMite tool? It can automatically whittle
down your code into a minimal test case.
