D compiler equivilent of "gcc -E" for debug/view template instantiation(generated) code?

[dangbinghoo]

hi, is there any D compiler option or other method to view the 
final template instantiation but not compiled (in asm or binary) 
code?

if there's a way, it might be very usefull for newbies like me to 
learn and understand the the Meta programming of dlang.



thanks!
