I'm not sure why they chose not to include a pragma to switch to Perl5 parsing, but Perl6 syntax is supposed to be mutable, so you could see it happen.
That said you will be able to do 
use Old::Perl5::Style::Module; #I'm assuming this exports old_perl5_st
+yle_code by default

old_perl5_style_code();
