Only global variables can be initialized that way.
The behaviour is undefined when targeting a ROM-based platform.
For every variable `x` larger than a byte, extra subvariables are defined:
* if `x` is of type `word` or `pointer`:
* constituent bytes, from low to high: `x.lo`, `x.hi`
* if `x` is of type `farword`:
* constituent bytes, from low to high: `x.b0`, `x.b1`, `x.b2`
* partial words: `x.loword` (=`x.b1:x.b0`), `x.hiword` (=`x.b2:x.b1`)
* if `x` is of type `long`:
* constituent bytes, from low to high: `x.b0`, `x.b1`, `x.b2`, `x.b3`
* partial words: `x.loword` (=`x.b1:x.b0`), `x.hiword` (=`x.b3:x.b2`)
