I keep having to close everything in order not to get an out of memory error
while compiling (-w -full).
I'd like to get it from 700-800 to below 400 :)
Any way to inspect which part is the biggest drain?

450 to below 300 pls :)

CTFE and templates will use up the most memory - particularly if you use 
a lot of strings, as the memory allocated is never freed. You can work 
around it be compiling files one at a time or a few at a time, so 
instead of:

$ dmd file1.d file2.d

Use:

$ dmd -c file1.d
$ dmd -c file2.d
$ dmd file1.o file2.o

Note if you're doing this you may like to look into the -op option to 
avoid object file conflicts which will lead to linker errors.

Compiling main alone tops 400MB :D
dmd -c -w proj_1\main.d

The hassle is probably not worth the money for new memory.. if only I wasn't
broke :D
