When enabled, the Rego compiler has an expanded set of constraints,
which will be treated as errors when violated. E.g. duplicate imports, unused local variable
assignments, shadowing of reserved 'input' and 'data' keywords, and use of some deprecated built-in
Coverage explains which statements were evaluated. Red expressions were never evaluated. Red rule
heads were never defined. Green expressions were evaluated at least once. Green rule heads were
defined at least once.
Built-in Error Behaviour
By default, built-in function errors are ignored, results will be from non-erroring code paths.
If Strict is selected, execution will exit early when the first built-in function
error is encountered.
If Show All is selected, all built-in errors from all code paths will be returned
as an errors.
