    Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.

    In Australia, this gauge is typically referred to as narrow gauge in comparison to 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge or 5 ft 3 in (1,600 mm) broad gauge. In some instances, simply 3 foot 6 inch — or in rarer cases medium gauge — is used to distinguish it from other narrow gauges.

    Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [2] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2, 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4-inch ...
