sysctl(8) is already able to use mixed numeric/string paths:

> sysctl proc.$$.stopfork
proc.11373.stopfork = 0

To avoid amibiguities, I say that a digits-only name MUST match the
integer name.  That is, this should not be allowed:

sysctl_createv(NULL, 0,
               NULL, &cnode,
               CTLFLAG_PERMANENT, CTLTYPE_NODE, "17", NULL,
               NULL, 0, NULL, 0, 12, 3, CTL_EOL);

because that would create a node with the numeric path 12.3 whose string
path ends in "17".
