Optimization: a Stack/Heap approach

[thysultan]

Instead of

body {
  color: red
}

producing

[
  [RULE_START, 1],
    [SELECTOR, 'body'],
    [PROPERTY, 'color'],
    [VALUE, 'red']
  [RULE_END]
]

It could instead produce

HEAP = ['body', 'color', 'red']

[
RULE_START, 0,
SELECTOR, 0,
PROPERTY, 1,
VALUE, 2,
RULE_END, 2
]

Where the ints 0,1,2 are memory addresses for the corresponding values in the HEAP.

This way you can use a flat Uint32Array typed array for maximum throughput on performance.
