Are you sure? That doesn't sound right.
I know this is the case for void[] - even though you can't put
pointers in it, it could hold "anything", so the GC strays on the
safe side and assumes it has pointers.
There was (is?) a problem with e.g. std.file.read("a") ~
std.file.read("b") - even though read marked the memory as not
containing pointers, the result of concatenation is a new void[],
which the GC thinks might contain pointers.
