I agree. And it's probably not going to be a hard patch. But there will be the backwards compatability police - as adding 'say' as a keyword might possibly break existing code.

Funny. Seems it might "break" one module I made a long, long time ago:

sub say { print(STDOUT @_); if ($_[$#_] !~ /\n$/) { print(STDOUT "\n"); } }
As far as I can tell, it was written in 1997 or 1998. I can live with that breaking (it seems to be doing something similar to Perl6::Say anyway - although I can't tell anymore whether adding the newline, or the printing to STDOUT was the main feature for it). But, if proposed, someone is bound to make the unsupported claim that "thousands and thousands of programs will be broken".

Hmmm, looking at the code I digged up I can see the charm of a print function that adds a newline only if the string to print doesn't end with a newline. Kind of like chomp only chopping of newlines.
