Running this from the command line produces (exactly?) the same 
error...

me at ubuntu:~/src$ rdmd sample.d sample_a.d
/tmp/.rdmd-1000/rdmd-sample.d-94E53075E2E84D963426A11F2B81FDED/objs/sample.o: 
In function `_Dmain':
sample.d:(.text._Dmain+0xa): undefined reference to 
`_D8sample_a1A7__ClassZ'
collect2: error: ld returned 1 exit status
--- errorlevel 1

I tried swapping the order of the file names, but that didn't 
help.

Ah. I thought that the purpose of "rdmd" (as opposed to "dmd") 
was to link the files automatically. Thanks.
