Inconsistency in the second argument to map, filter etc
Imported from http://bugzilla.roxen.com/bugzilla/show_bug.cgi?id=3150
Reported by Martin Stjernholm mast@roxen.com
According to the doc and the types for map and filter, they can be called with only one argument if it's an array containing functions. Yet that yields the compile time error "Too few arguments to map() or filter()!".
The same problem exists in 7.2 and 7.0.
