compiling this code with -c -o- switches yields no error messages, while
compilation with -c switch yields error.

dmd -c tmp.d -o- -I.. -w


dmd -c tmp.d -I.. -w


isn't implemented

that's not a bug if you look at it a different way; -o- is to allow generating
ddoc output without having to run everything. 

OTOH if you see it as run a test build but don't generate object files...

not everything, just object file generation

well then this feature should be better documented, because *some* semantic
analysis is *done* with -o- switch. I suspect that this surprise only pops up
when compiler tries to build class's vtbl at codegen step, which means that
semantic analysis is not fully done at right time. I intensively use gcc
-fsyntax-only and never run into trouble with it, in spite of the switch name,
it seems like it does full semantic analysis.

At some point I home that DMD will actual do more semantic stuff under -o- as
then I can get DDoc output for generated code. However even then DMD should
only do what is needed to generate the requested output.

DMD actually does quite a bit of error handling during code generation. I've
been hit by this several times in LDC, where it means that quite a lot of the
time, you can't be sure the AST you're generating code for is valid.

I would love to see this fixed as well, but I can also understand that some
errors are a lot simpler to detect at the codegen stage, so it worth the
performance tradeoff ?

I'm not sure.
