TODO.txt

- Extend a quantumn bariable by one extra bit 101 becomes 0101

- Create qutatum variable of size guven by classical   int a = 5    qN: b = 10

- CX gate on variables allow different size inputs

- Decide if to allow controlled-swap

- there is apperently a |0> reset gate. then early measurement is compulsory.

- also a if on classsical gate.

- allow a[0] = H(a[0]);

- Do the persist kill in a bit level. Run this and then draw
	fn main() {
    a: q3 = 0;
    a[0] = H(a[0]);
    b: q1 = 1;
    a[1] = X(b);
    a
	}

- ADD a shor hand "H(a[0])" to mean "a[0] = H(b)"

- Mutiplexer
    a = if_qm(a[0]){a[]}

- prevent errors like cx q[0] q[0]

- Divide AST into several files

- Make function out of common stuff.

- Force reset after every operation and persist if needed later.

-Define persist in a way so that a[0] keeps a new copy of only a[0]

- a = 2 + 3 + 4 ..... constant fold to a = 9

- to handel expr = if_qm(){}{}. 

c = if_qm(){}{}
a = c + b

- Error message when try to set varaible name with keyword

-REMEMBER IF ELSE PART NOT MENTIONED ITS TAKEN AS if(){}else{0}
- check what happens for a = a + 1 now

- DO Q-3AC or this will mess up persist kill as threre can be mutiple temp on a single variable

-Define constants to be imported as fn abc(){5}  then call as i.abc

- A Debug mode where it shows the values in the Qubit lines after each line is executed by pressing <enter> can convert stuff to zero[stop displaying value of that qubit] in simulator as no entanglement issue

- Single unidifed data type thing become qubit on superposition untill then they are classical. Must allow "a:3 = 0" or "a:3 = max" so one can get |----> and |++++> on H

- Replace ASTId.persist_status's data type from str to something more optimal

- id add(a:q7) and we give a q3 at call then increase it to q7

- Take info from function to get better idea od persist kill- currently we are just choosing which function to use.

- maybe we should allow  a: c = 5    b : q{a} = 0 to get |00000> 

- Make persist kill mechanism only have the quantum data

- Do Persist-kill inside functions also maybe like the way of doing a new context

- ["w",None,'a'] add something for classical in middle
