Hi stsp,
I noticed in the recent gsm0808_cell_id_list2 a review item slipped by:
A "LAI" is by definition a PLMN (MCC+MNC) plus a LAC.
So saying "LAI and LAC" is like saying "My family and my brother".
So maybe we want to rename the "lai_and_lac" member of struct
gsm0808_cell_id_list2 before it gets tagged for release. Just "lai" would be
accurate, as its type (struct osmo_location_area_id) suggests.

I noticed that the CELL_IDENT enum has a similar quirk:
CELL_IDENT_LAI_AND_LAC
so it probably came from that.
I think we should rename it and have a backwards compat:
#define CELL_IDENT_LAI_AND_LAC CELL_IDENT_LAI

Yes, this is where it came from.
I think we should rename it and have a backwards
compat:
#define CELL_IDENT_LAI_AND_LAC CELL_IDENT_LAI
The standard from 1999 (TS 08.08 section 3.2.2.27 "Cell Identifier list")
calls it just "LAI":
"Location Area Identification, LAI, is used to identify all cells
within a Location Area"
So I would agree with your proposal.
