Exactly. Its a convention, the same one as the _Type convention for Ada,
except that it is used consistently in the base Dylan language, and I
personally find it easier to read than _Type. I'm aware that opinions will
differ.

I don't like this, but I imagine if I spend every day for a few days
staring at consistently formatted Eiffel code I'd come around. However,
I'd also suggest that some amount of type inference in the language would
remove some of the burden of name invention, and thats generally a good
thing.
No comment on your new signature ;-).
