Could be used as a compact alternative to the following compound foreach construct:
foreach feature [$shp coord read] record [$shp attr read] {
# process feature and record
}
The [read] method would return a two-element list containing the coordinate list and the attribute record. With no index argument, these lists would include all entities; with an index argument, they would be the coordinate and attribute data of the specified index.
foreach {feature record} [$shp read] {
# process feature and record
}
