Can we just have struct inheritence already?

C++ is more so the one with how long it takes to compile. C isn't 
that bad. I don't see anything replacing C, there are a number of 
different languages that could but they are all fragmented.

DMD can eat a lot of memory, it also isn't very efficient.

static foreach(i; 0 .. 0xFFFF) {}

the above code eats up over 12 GB of RAM. That's all my free RAM 
+ whatever it is using on my drive. It also takes a REALLY long 
time to execute, at least an hour. I gave up after that. Spends 
almost all of it's time doing Array operations. DMD has a really 
weird implementation of Array, looks like it was implemented 
possibly in D1 days. Reserve(int) is additive, sure fine w/e. 
Passing around arrays as points, so need to dereference them to 
actually use them... Then you have insert(Range) that does a 
reserve(), which allocates new memory, copies all the data. Then 
the insert moves all the data it just copied. Sure the code is 
simpler but it has horrible performance, especially when there is 
a loop that is constantly adding and removing from the 
front/middle of the array.
