In these examples, we can identify the constructor (capitalized first letter) on the LHS and so we are trained to know that it is a pattern match. The original point related to number specialness was that "1 = 2" is not easily identifiable as a pattern match because there are no explicit constructors. The literal "1" here is neither an "explicit constructor" nor a binding symbol.
Yes, at this point you just have to know that the Report specifies a bunch of special handling for numeric literals. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
