Abstract
Transient gradual typing imposes run-time type tests that typically cause a linear slowdown in
programs’ performance. This performance impact discourages the use of type annotations because
adding types to a program makes the program slower. A virtual machine can employ standard justin-time optimizations to reduce the overhead of transient checks to near zero. These optimizations
can give gradually-typed languages performance comparable to state-of-the-art dynamic languages,
so programmers can add types to their code without affecting their programs’ performance.
