type FieldLabelString = FastString Source #
Field labels are just represented as strings; they are not necessarily unique (even within a module)
type FieldLabelEnv = DFastStringEnv FieldLabel Source #
A map from labels to all the auxiliary information
Fields in an algebraic record type

Record selector OccNames are built from the underlying field name and the name of the first data constructor of the type, to support duplicate record field names. See Note [Why selector names include data constructors].
