I'm guessing that what you meant was "say as a function was what I meant to
use there." In which case:
say for reverse lines
or
for reverse lines { say }
These are both valid ways of asking for each element of the iterable thing
returned from lines to be printed with a newline.
But remember that any {} around code creates a Block in Perl 6, and a Block
is a first-class object. If you ask say to print a Block, it will quite
happily try to do that.
