Dynamic typing: syntax and proof theory by Fritz Henglein

http://www.diku.dk/hjemmesider/ansatte/henglein/papers/henglein1994d.pdf

We present the dynamically typed λ-calculus, an extension of the statically typed λ-calculus with a special type Dyn and explicit dynamic type coercions corresponding to run-time type tagging and type check-and-untag operations. Programs in run-time typed languages can be interpreted in the dynamically typed λ-calculus via a nondeterministic completion process that inserts explicit coercions and type declarations such that a well-typed term results.
