[Big Ints], more than 32- or 64-bits.
 
[High-Order Functions] accept functions as parameters and/or return functions as results.
 
[Parser] (recursive descent) for expressions.
 
[Lazy data types] are not standard in SML but they can be implemented in the language.
 
[Structures, signatures, functors], struct, sig.
 
[Continuations] can be used to implement non-standard control mechanisms.
 
[Fixed-point operator, `Y'], note that Y does not refer to itself within its body, nor does the local function Ggg; one could rewrite Y to consist of only anonymous functions. Also see [λ/Y].
 
[semantics.toy] direct denotational sematics of a toy imperative language expressed in SML-97
