 Flow- and type-analysis only enabled with the `-scrutinize` or
 `-specialize` options, or when an optimization-level > 2 is selected.
 Since the type-analysis can catch many errors, sjamaan suggested to enable
 scrutiny by default (note that this doesn't automatically imply
 specialization, i.e. optimizations based on the analysis).

 To avoid incorrect warnings in code that redefines standard bindings,
 scrutiny should be disabled when the `-no-usual-integrations` option
 (implied by optimization level 0) is given.
