public void insert(Identifier name,
                   T value)

insertFact

public void insertFact(Expr name,
                       T value)

toString
```
public String toString()
```
Overrides:

toString in class Object

eval
```
public Optional<T> eval(Expr expr)
```
Search the fact stack for an explicitly calculated value for [expr]
Currently, this is only impacted by the `isSet` function which will record `T`, rather than Option<T> for its arguments

Parameters:

expr - The expression to evaluate

Returns:

The value from the scope

expectValue

public T expectValue(Identifier name)

getValue

public Optional<T> getValue(Identifier name)
