Well yes, dynamic arrays require the GC and hence TypeInfo. Slices 
don't, but that isn't a slice as it isn't from some random malloc'd memory.

this line:

is an dynamic array allocated with GC.
But if you declare as a static array like
byte[2] data = [0, 1];



than its not GC allocated.

Or use C malloc.

We really should provide better tools to create arrays using C malloc 
(for those who want them). Like a betterC toolkit.

Indeed, i´m creating my own "toolkit" for betterC stuff like
alloc!Type(length); (much safer than malloc!) and other utilities 
:)

Need to declare main() like those C people do:

Thanks for all you help, the betteC is really useful and handy.

I am try to made mobile app (right now IOS), seems Dan Olson 's 
great IOS work is stopped since 2 years ago.

Hope the D community get better and better with more betterC 
Cross platform support.
