These were committed in r13095 and then reverted out of the working copy while
undoing an unrelated bad edit to the same file. The commit stands; the working
copy did not, and later work was built without them. Restored and verified
against the programs that first showed each:
- a struct with a field initialiser needs an explicit parameterless
constructor, and an array member is emitted with an initialiser
- two WHEN clauses may test the same value; 4GL runs the first that matches
and a C# switch rejects duplicate labels, so those take the if/else
fallback that already existed
- the keyword escape must not survive into a flattened identifier -
"InVar_a_@..." does not parse, and the flattened name cannot be a keyword
The lesson is narrower than it looks: revert takes the whole file, so undoing
one edit to a file that carries several loses the rest.
