Yes, because Perl 6 *is* Perl 5, when it wants to be.

Correct. If you *say* "perl6" and then want to *be* Perl 5, I'm not sure
if a) you could not or b) you would have to throw in something like "use
5".

Not sure why. That is just short-hand for:
#!/usr/bin/perl
use 5;
I'm not sure, once again, what would happen if you said:
use 5;
use 6;
Either it would give you an error (you really deserve it) or it would
just switch back to Perl 6 mode... the problem arises when you ask,
"what about anything that got parsed in between the two?" Yech.
