That's expected indeed.

This doesn't mean the inliner will not inline the templates. In fact, 
if you correct the example and look at the assembler output you'll see 
it will (in your example there is nothing to inline since you're just 
instantiating the template without calling it).

What doesn't happen is stripping the unreferenced symbols from the 
executable. On OS X, try adding "-L-dead_strip" to DMD's argument to 
instruct the linker to do so.
