You can also write “context.setvalue(start..foo,…)” but table.concat
looks better but the question is why don’t you use just tex
to create the start/stop commands.

This would just create \startfoo. \setvalue{\e!start foo} creates a 
interface specific command. The code that Hans posted does that. I am 
sorry that this was not clear in the question.

OK.

Because I find it much easier to understand expansion at lua level than at 
TeX level.

start[currentinterface] = start[interface]

a next beta will have interfaces.elements
