//: Clean syntax to manipulate and check the console in scenarios.
//: Instruction 'assume-console' implicitly creates a variable called
//: 'console' that is accessible inside other 'run' instructions in the
//: scenario. Like with the fake screen, 'assume-console' transparently
//: supports unicode.
//: first make sure we don't mangle this instruction in other transforms
