IIRC, it used to be restricted to a constant, a few revisions back.
In current releases the only restriction that stems from laziness is
not allowing a sub-select. (If anyone were to put forward a serious
use-case, we'd probably go fix that.)
The OP's complaint is that we don't allow a variable of the query's own
level, but AFAICT he's still not grasped the point that that leads to an
indeterminate limit value ...
