bracket abstraction
An {algorithm} which turns a term into a function
of some variable. The result of using bracket abstraction on
T with respect to variable v, written as [v]T, is a term
containing no occurrences of v and denoting a function f such
that f v = T. This defines the function f = (\ v . T). Using
bracket abstraction and {currying} we can define a language
without {bound variable}s in which the only operation is
{monadic} function application.
See {combinator}.
