My view is that typing strings by means of patterns should always
exhaust the string as the above pattern does. I can imagine some
magic that lets
my KeyName @a = "First Second";
allow to actually have two entries @a[0] eq "First"
and @a[1] eq "Second" by somehow morphing the pattern into
continued matching mode where the next index continues where
the previous left off---and skipping whitespace.
Just an idea...
