final class Abs extends ConcreteTerm
A lambda abstraction (ML constructor Abs). name is the name of the bound variable,
typ is the type of the bound variable, and body is the body of the lambda abstraction.
E.g., λx. x would be represented as Abs("x",typ, Bound(0)) for suitable typ.
Note that name is for informative purposes only (i.e., it has no logical relevance)
since deBrujn indices are used. name can even be "".

Equality of terms.
Equality of terms. Returns true iff the two Term instances represent the same term in the Isabelle process. (E.g., a Cterm and a Const can be equal.) May throw an exception if the computation of the terms fails. (But will not fail if await or a related FutureValue method has returned successfully on both terms.)

- lazy val someFuture: Future[Any]
Returns a future that completes when the computation of this object is complete.
Returns a future that completes when the computation of this object is complete. (Or that holds an exception if that computation throws an exception.) However, upon successful completion, the future may return an arbitrary (and thus useless) value. May be faster to implement than forceFuture because there may be already a future available but that returns the wrong value.

A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.
A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.
This can be useful to constructing human readable messages about this value.

- def toString: String
Produces a string representation of this term.
Produces a string representation of this term.
This is not a "pretty" representation, it does not use Isabelle syntax, and subterms that are stored only in the Isabelle process are replaced with a placeholder (thus this method does not invoke any potentially communication with the Isabelle process).
