Any such functional languages are brain-dead. The non-strict (often sloppily
[and I'm no exception!] referred to as "lazy") languages permit circular
structures as in eg

    let rec ones = cons( 1, ones )

[The syntax, of course, varies]. The strict languages (such as ML and Scheme,
if we permit them to enjoy the adjective "functional") contain assignments
which permits the construction of circular structures.
