In *all* contexts, it's a supercomma. C<..> interprets whatever comes
after the supercomma as being a step.

They can be variables in Perl 5, so I suspect Perl 6 is fine with it
too.

This isn't a syntax error, but it doesn't do what you want.
# 1 .. $a
# 1 .. $a : 2
# $a .. $b
# $a .. $b : 2
# $a .. $b : $c
# 1 .. 10 : $c
# 2.5 .. 10.0 : 0.5
To my knowledge, these are all fine.
