issue57949

This is a program to collect data for https://github.com/golang/go/issues/57949

It follows the normal go tool conventions via go/packages.

It counts keyed struct literals. It specifically counts the following patterns

key: identifier,
key: qualified.identifier,
key: *identifier,
key: *qualified.identifier,
key: &identifier,
key: &qualified.identifier,

For each of these patterns it also records when key and identifier match exactly or partially. == is used for an exact match. A partial match are not counted for patterns with a qualified identifier and uses x != y && strings.EqualFold(x, y). Partial matches are for cases such as Title: title.

Results are per-package followed by a total of all packages queried.
