Good point, though I updated my reply a bit while you were replying. But you didn't give me time to correct a typo in the word existence :)
Anyway, the best way to check would be
type('m.MyVar') <> 'U'
or vartype(m.MyVar) <> 'U'
to make sure we're talking about variables and not field names.
If it's not broken, fix it until it is.
