(cons-stream a b)syntax

Is equivalent to (cons a (delay b)). See SICP Section 3.5.1.

Remark: The necessity to include cons-stream is due to the fact that SICP does not introduce any syntax-altering constructs beyond writing your own metacircular interpreter. Please note that the stream-cons procedure from SRFI 41 (implementing "even" streams) would not be a drop-in replacement for cons-stream.
