I try to write something on this once a week, though longer posts 
like this tend to be less common (and some weeks, like last week, 
I post nothing at all...), but I rarely post here since I don't 
want to be super spammy.

However a reminder here my D blog is still active and if you use 
my libs you might want to check in once a month or so and if you 
don't, the general D tips are probably interesting enough for you 
to skim anyway every two or three months.

Anyway, I wrote something longer this time and talked both about 
my libs and about some dmd compile speed/ram tips in general so 
might be worth a skim by many of you:

(and a couple weeks ago I wrote about the script lang too which 
if you are at all interested in that it might be fun to look at:

you can subclass D classes in script and reuse them from D! 
pretty cool if i do say so myself lol)

Yah static foreach is slow for sure. Part of the problem is that it literally just runs a lambda at CTFE that creates a tuple. So that static foreach 0 .. 10000 literally creates a tuple with 10000 elements. Might even create an array first that then gets converted to that tuple. So yah, not very efficient at all.
