Looking at the asm produced by a system language is often useful, to know if a function was inlined, to see if the compiler has done certain expected optimizations, to verify certain compiler bugs, to compare the quality of a D compiler to a C or C++ compiler on similar code, to learn to write assembly, and so on.
There are some ways to read the asm produced by the D compiler (like using obj2asm) but I suggest to add to DMD a compiler switch similar to "-S" of GCC to output the asm from the compiler itself.
There was a request for it in D.learn too:

Unlike gcc, the dmd backend generates machine code directly instead of generating assembly. You would need to pass the code through a disassembler in order to display the assembly.
This is never going to happen, especially given how easy it is to just use objconv/objdump.

We did eventually add that, it's the -vasm switch.
