hi, is there any D compiler option or other method to view the

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

Not sure if this is exactly what you want but there is a hidden 
switch in dmd called `-vcg-ast` that prints out all the templates 
instantiated.

On run.dlang.io you can use the "AST" button to view this 
conveniently online.

but, where's these switch option documented? it seems it not 
appears in dmd --help or man dmd, or online document 
https://dlang.org/dmd-linux.html

That's what he meant by "hidden" switch. I don't know why it 
isn't documented, but it probably should be.

The reason why it's not documented is because we don't want 
people to rely on the format of the output.
I guess if we put that disclaimer in the docs we could ...
