Thanks! You'd think that to would do this internally
automatically ;/
It only works on literals.

You cannot do that.

Hi there,
I've just adjusted the memory allocation behavior.
newCTFE will now start-out allocating 32M of memory at startup.
and increase the allocated space in 8x steps if it hits the limit
while executing concat code.

Hi Guys,
I've fixed a few ABI bugs and as a result my alternative to
std.bitmanip.bitfields complies now.
I've also made an intrinsic for the concat operation.
Which causes ~= to be 6-10x faster when it's heavily used.

If you're keen to introduce a new function, I'd strongly
suggest changing to {1} {2} {3}, or %1 %2 %3, format/printf
functions where you don't supply the place in

I am quite surprised.
newCTFE comes far enough now, that it tries to interpret it's own
interpreter (which is CTFEable)
Of course it fails in doing so since we do not yet handle newing
arrays or associative arrays.

The following code does now compile with newCTFE,
and it's a little faster then the old interpreter.
Not much though since that is not a pathological case.

After a surprisingly small amount of work we are now supporting
pointers to array-items.
It should be quite doable to add bounds-checked pointer with
minimal amount of work.
