On my 64-bit linux machine my small application is taking as much as 2.2GB of RAM at the time of compiling the code using DMD 2.059. I am using the latest Pegged code from github.

It really appears to be that heavy - i once tried to use it for some compile time
parsing, but it turned out that just importing the module was so expensive (added
seconds to every compiler invocation, iirc) and it got disqualified before i even 
had a chance to try it...
