It's not a good mindset to have

Ironically, dmd itself is pretty care-free about allocating
memory (in the name of compile speed -- after all, everybody
has GBs of RAM to spare, but nobody wants to wait, right?). As
a result, I cannot compile even simple programs on a low-memory
system because the compiler runs out of memory and crashes
before it can finish compiling. What good is a super-fast
compiler that cannot finish compiling before it uses too much
memory? Because of this, I have not dared to introduce D to my
colleagues -- if they see what dmd does on the kind of
low-memory embedded systems that we work on, they'd get such a
bad impression of D they'll never ever want to hear about it
again. :-/

I still remember compiling code on my 286x86 ... talk about low
memory..whoaaah.
These days, I have a 4GB ramdisk, put all the dmd/phobos..etc
source code into that, and everything is read/compiled completely
in memory, in seconds. The slowest part is copying the
compilation back to disk, but even that happens so fast I don't
even see it happen.
Worrying about an extra allocation here or there seems kinds
trivial over here ;-)
