Period works okay if Period followed by whitespace is an expression
separator, and period followed by a printable character can be part of a
name.

What's a variadic message?

I'm not sure what the status of underscores are. Currently I think they're
still a hack for the back-arrow in the squeak image, and from what I hear
they are not accepted in Croquet? It is possible to free them up and make
people use either a Unicode back-arrow :-) or :=.
