you can subscribe to multiple events.

Alternatively, yes you ca do it the way we are dealing with different
browsers: have a map of internal representation to actual one. In
general it can be represented as:
``` javascript
function get_node_ver() {
// some decisions and return as `06` for `0.6.x`, etc.
}
var EVENTS = {
'06': {
exit: 'death',
// ...
},
'08': {
exit: 'exit',
// ...
}
};
EVENTS = EVENTS[get_node_ver()];
```
