[rules-users] Setting value in LHS for access in RHS

[Michael Anstis]

Not sure I still understand ;)

Do you mean to use the *field name* (not it's value) in the RHS; e.g.

AccountExposure( $exp : cheese )
then
insert( new LimitCheck( "cheese" ) );

If so this is not possible without repeating the enum in the [then] DSL
sentence but obviously users could easily select different values for each.

At the moment I would have to suggest different DSL sentences is probably
your only option.

Or, a different check type dependent on the exposure type?

AccountExposure( $exp : cheese )
then
insert( new CheeseCheck( $exp ) );

???
