Does 'D' language supports 'C' like VLA?

As you know in 'C' you can create a variable-length-array using
variably modified type and a run-time variable allocating a
storage for it - the same way for any local (normally using the
stack).
However in 'D' I don't see such feature. Code like this fails:
void main()
{
size_t szArr = 3;
int[szArr] arr;
}
With this error message:
error: variable szArr cannot be read at compile time
int[szArr] arr;

Note: I'm also amazed why 'D' compiler can't detect that 'szArr'
is a constant anyway.
