automate tuple creation

[forkit]

so I have this code below, that creates an array of tuples.

but instead of hardcoding 5 tuples (or hardcoding any amount of 
tuples),
what I really want to do is automate the creation of 
how-ever-many tuples I ask for:

i.e.

instead of calling this: createBoolMatrix(mArrBool);
I would call something like this: createBoolMatrix(mArrBool,5); 
// create an array of 5 typles.

Some ideas about direction would be welcome ;-)

@safe:

void main()
{
     uint[][] mArrBool;
     createBoolMatrix(mArrBool);
     process(mArrBool);
}

void process(T)(const ref T t) if (isForwardRange!T && 
!isInfinite!T)
{
     t.writeln; // sample output -> [[0, 1], [1, 0], [1, 1], [1, 
1], [1, 1]]
}

void createBoolMatrix(ref uint[][] m)
{
     auto rnd = Random(unpredictableSeed);

     // btw. below does register with -profile=gc
     m = [ [cast(uint)rnd.dice(0.6, 1.4), cast(uint)rnd.dice(0.4, 
1.6)].randomShuffle(rnd),
           [cast(uint)rnd.dice(0.6, 1.4), cast(uint)rnd.dice(0.4, 
1.6)].randomShuffle(rnd),
           [cast(uint)rnd.dice(0.6, 1.4), cast(uint)rnd.dice(0.4,
