I don't think we knowingly made 'text' not be allowed as a variable in 
non-explicitVariables mode...

You cannot explicitly declare `tExt` as a variable in 10 or 9.x or (I 
think) ever - but it obviously worked in 9.6.x and before if you don't 
use explicitVariables.

I'm not sure what change we've made which has caused that - file a bug 
and we'll look into it - its probably a regression, but could be a 
(necessary, but unrealized) side-effect of another change we've made
