If you look up %w at the beginning of the index in pickaxe2, it directs 
you to p. 322, which has a section titled Arrays.  In that section, it 
says %w is a form of general delimited input described on p. 318-319. 
Looking on those pages, it says:

"Following the type character is a delimiter, which can be any 
nonalphabetic or nonmultibyte character.  If the delimiter is one of the 
characters (, [, {, or <, ....blah, blah, blah...[the ending character 
must be: ), ], }, or > respectively].  For all other delimiters, [the 
ending character is the next occurrence of the starting delimiter]."
