The code from the opening post now fails to compile in DMD v2.083.1 and the
linker won't be called. That's good.

But ag0aep6g's reduced case from Comment 6 --
https://issues.dlang.org/show_bug.cgi?id=15459#c6 -- still compiles with DMD
v2.083.1 on 64-bit Linux, then fails to link. Linker error below. Expected
instead: That code should fail compilation, as annotated via /* should fail
compilation */.

    /usr/bin/ld: a.o: in function `_D1a__T3mapZQfFNaNbNiNfZv':
    a.d:(.text._D1a__T3mapZQfFNaNbNiNfZv[_D1a__T3mapZQfFNaNbNiNfZv]+0x27):
undefined reference to
`_D1a__T9MapResultZQl6__ctorMFNaNbNcNiNfAaZSQBp__TQBqZQBu'
    collect2: error: ld returned 1 exit status
    Error: linker exited with status 1

Or should we file a separate bug for that?
