This makes more sense.  In some cases, the contracts would be
implemented manually (eg, primitives), etc.  So running it in a
sandbox makes the most sense in terms of getting safe executions as
well as limiting the time you wait for each try.

*However*, there's an awful lot of functions to try -- going over them
will make a very slow search...
