If the type is variable it can be used an associative array of variants, but things become more complex. Adding a name to all instances of a class can be possible. |

ELENA does not support adding a variable at run-time but it can be simulated with the help of a group object |
|||
<lang elena>#subject foo. |
|||
#class Object |
|||
{ |
|||
} |
|||
#class FieldContainer |
|||
{ |
|||
#field theValue. |
|||
#method foo'set : anObject |
|||
[ |
|||
theValue := anObject. |
|||
] |
|||
#method foo'get = theValue. |
|||
} |
|||
#symbol Program => |
|||
[ |
|||
#var anObject := Object. |
|||
// adding a field |
|||
anObject := #group(anObject, FieldContainer). |
|||
anObject set &foo:"bar". |
|||
'program'Output << anObject foo. |
|||
]. |
