for-loops #297

What if you used for-loops only to address data structures with known size during compilation.

for example:
`sm = 0
mat = [
[1, 2],
[3, 4],
]

for i in range(len(mat)):
for j in range(len(mat[0])):
sm += mat[i][j]
print(sm)`

Could you turn this into (mat[0][0] + mat[0][1]) + (mat[1][0] + mat[1][1])?
Do you think that it would be useful?
Would it bloat the executable too much?
