Query: Functional Choreographic Programming   Choreographic programming is an emerging programming paradigm for concurrent
and distributed systems, whereby developers write the communications that
should be enacted and then a distributed implementation is automatically
obtained by means of a compiler. Theories of choreographic programming
typically come with strong theoretical guarantees about the compilation
process, most notably: the generated implementations operationally correspond
to their source choreographies and are deadlock-free.
  Currently, the most advanced incarnation of the paradigm is Choral, an
object-oriented choreographic programming language that targets Java. Choral
deviated significantly from known theories of choreographies, and introduced
the possibility of expressing higher-order choreographies (choreographies
parameterised over choreographies) that are fully distributed. As a
consequence, it is unclear if the usual guarantees of choreographies can still
hold in the more general setting of higher-order ones.
  We introduce Chor{\lambda}, the first functional choreographic programming
language: it introduces a new formulation of the standard communication
primitive found in choreographies as a function, and it is based upon the
{\lambda}-calculus. Chor{\lambda} is the first theory that explains the core
ideas of higher-order choreographic programming (as in Choral). Bridging the
gap between practice and theory requires developing a new evaluation strategy
and typing discipline for {\lambda} terms that accounts for the distributed
nature of computation in choreographies. We illustrate the expressivity of
Chor{\lambda} with a series of examples, which include reconstructions of the
key examples from the original presentation of Choral. Our theory supports the
expected properties of choreographic programming and bridges the gap between
the communities of functional and choreographic programming.
