I'd like to do access State#record_name.field like this:
Variable = field,
State#record_name.Variable.
That is, I do not know which field I need, but variable Variable knows. Is that possible?
What I'm trying to do is take a list of fields, iterate over it and return list of {field, value} pairs. Is this possible in erlang?
Regards,

| No, there is no way of doing this in erlang. Records are a purely compile time feature and are implemented in an early pass in the compiler where they are translated to normal tuple operations. |
