[rules-users] Setting a value in LHS

[Michael Anstis]

This would need to be provided by the tooling; I don't think it's something
that's even remotely possible at runtime (unless you stored the field name
in a Fact and used reflection on the RHS).

That said (and you're going to guess my next comment) this is not provided
in the guided editors. Depending on how complex your DSLs are and whether
users need to combine DSL Sentences; IDK if a "cheat" works:

[when]Do something with {field} and {value}=$f : Fact({field}=={value} then
$f.{field} = {value}

I've not tried it; nor know whether it fits your requirements.. but a hack
worth trying?
